Herein we report the synthesis of substituted indolizidines and related N-fused bicycles from simple saturated cyclic amines through sequential C-H and C-C bond functionalizations. Inspired by the Norrish-Yang Type II reaction, C-H functionalization of azacycles is achieved by forming alpha-hydroxy-beta-lactams from precursor alpha-ketoamide derivatives under mild, visible light conditions. Selective cleavage of the distal C(sp(2))-C(sp(3)) bond in alpha-hydroxy-beta-lactams using a Rh-complex leads to alpha-acyl intermediates which undergo sequential Rh-catalyzed decarbonylation, 1,4-addition to an electrophile, and aldol cyclization, to afford N-fused bicycles including indolizidines. Computational studies provide mechanistic insight into the observed positional selectivity of C-C cleavage, which depends strongly on the groups bound to Rh trans to the phosphine ligand.

Category: esters-buliding-blocks. I found the field of Chemistry; Physics very interesting. Saw the article In situ preparation of palladium nanoparticles in ionic liquid crystal microemulsion and their application in Heck reaction published in 2020.0, Reprint Addresses Umadevi, S (corresponding author), Alagappa Univ, Dept Ind Chem, Karaikkudi 630003, Tamil Nadu, India.. The CAS is 103-26-4. Through research, I have a further understanding and discovery of Methyl 3-phenyl-2-propenoate.

A simple and an efficient approach for in situ preparation of palladium nanoparticles (Pd NPs) in ionic liquid crystal (ILC) microemulsion is described. Microemulsion was formed by using a ternary mixture of triton X-100/ILC/water (in the ratio of 1.4:0.1:8.5). Three such microemulsions-1, 2 and 3 were formed by using three different ILCs namely ammonium ILC containing a cholesterol core (ILC-1), imidazolium ILC bearing a cholesterol core (ILC-2) and imidazolium ILC containing a biphenyl core (ILC-3), respectively. The Pd NPs were characterised using UV-vis spectroscopy, transmission electron microscopy and X-ray diffraction studies. Among the three, microemulsion-2 which was prepared using ILC-2 yielded stable NPs with an average particle size of similar to 20 nm. The NPs prepared in all three emulsions were examined as catalyst for Heck reaction. The catalytic efficiency was analysed for four cross-coupling reactions involving iodobenzene with different substituted alkenes namely methyl acrylate, ethyl acrylate, butyl acrylate and styrene. The coupling reactions were completed in a shorter period with good yields. Further, the recyclability test of Pd NPs revealed that the particles showed good activity until third catalytic cycle. The Pd NPs prepared in microemulsion-2 showed better activity compared to those prepared in microemulsions-1 and -3. (C) 2020 Elsevier B.V. All rights reserved.

The aim of this research was to determine the chemical constituents and toxicity of the oil derived from Alpinia katsumadai seeds against Tribolium castaneum, Liposcelis bostrychophila and Lasioderma serricorne. The essential oil was obtained by hydrodistillation and was investigated by gas chromatograhy/mass spectrometry (GC/MS). The principal components of the essential oil were methyl cinnamate (64.2 %), cis-4-decen-1-ol (7.3 %) and octahydro-cis-2H-Inden-2-one (6.7 %). The essential oil and the two individial compounds exhibited potential insecticidal activities against three stored product insects. The essential oil possessed contact toxicity against T. castaneum, L. serricorne and L. bostrychophila (LD50 = 52.6 mu g/adult, 17.4 mu g/adult and 35.6 mu g/cm(2), respectively). Methyl cinnamate was the main contributor to its contact activity against T. castaneum, L. serricorne and L. bostrychophila (LD50 = 5.0 mu g/adult, 2.2 mu g/adult and 23.5 mu g/cm, respectively). The contact toxicity and repellent activity of the essential oil and cis-4-decen-1-ol against T. castaneum, L. bostrychophila and L. serricorne were recorded for the first time in this paper. A. katsumadai oil exhibited strong repellent activity against T. castaneum and L. bostrychophila, even at low concentrations. The results provide a basis of the development and utilization as biopesticide for control of insects.

Regioselectivity for intramolecular Diels-Alder (IMDA) reactions of 6-acetoxy-6-alkenylcyclohexa-2,4-dien-1-ones that were formed by oxidation of 2-alkenylphenols with lead tetraacetate in acetic acid were studied. Bridged regioselectivity was observed in the IMDA reactions of 6-acetoxy-6-alkenylcyclohexa-2,4-dien-1-ones having a dienophile part which could conjugate with an aromatic group. Bridged seven-and eight-membered rings and bicyclo[2.2.2]octane skeletons were constructed by the present IMDA reactions. Density functional theory (DFT) calculations suggested that conjugation of the dienophile with neighboring aromatic groups lowered the highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) energy gap and preceded bridged [4 + 2] adducts.

Ambrosia beetles (Coleoptera: Scolytinae) cultivate their fungal symbiont within host substrates as the sole source of nutrition on which the larvae and adults must feed. To investigate a possible role for semiochemicals in this interaction, we characterized electrophysiological and behavioral responses of Xylosandrus germanus to volatiles associated with its fungal symbiont Ambrosiella grosmanniae. During still-air walking bioassays, X. germanus exhibited an arrestment response to volatiles of A. grosmanniae, but not antagonistic fungi Beauveria bassiana, Metarhizium brunneum, Trichoderma harzianum, the plant pathogen Fusarium proliferatum, or malt extract agar. Solid phase microextraction-gas chromatography-mass spectrometry identified 2-ethyl-1-hexanol, 2-phenylethanol, methyl benzoate and 3-methyl-1-butanol in emissions from A. grosmanniae; the latter two compounds were also detected in emissions from B. bassiana. Concentration-responses using electroantennography documented weak depolarizations to A. grosmanniae fungal volatiles, unlike the comparatively strong response to ethanol. When tested singly in walking bioassays, volatiles identified from A. grosmanniae elicited relatively weak arrestment responses, unlike the responses to ethanol. Xylosandrus germanus also exhibited weak or no long-range attraction to the fungal volatiles when tested singly during field trials in 2016-2018. None of the fungal volatiles enhanced attraction of X. germanus to ethanol when tested singly; in contrast, 2-phenylethanol and 3-methyl-1-butanol consistently reduced attraction to ethanol. Volatiles emitted by A. grosmanniae may represent short-range olfactory cues that could aid in distinguishing their nutritional fungal symbiont from other fungi, but these compounds are not likely to be useful as long-range attractants for improving detection or mass trapping tactics.

We report herein cobalt-catalyzed enantioselective and chemodivergent reactions between a cyclopropanol and an oxabicyclic alkene via a cobalt homoenolate, which afford either an alkylative ring-opening product or a hydroalkylation product, with the counterion of the cobalt catalyst being a major chemoselectivity-controlling factor. A catalyst generated from cobalt(II) chloride and a chiral diphosphine promotes alkylative ring opening to afford 1,2-dihydronaphthalen-1-ol derivatives in good yields with high enantioselectivity. By contrast, a catalyst generated from cobalt(II) acetate and the same diphosphine ligand, with the assistance of methanol, selectively affords hydroalkylation products with retention of the bicyclic structure at a comparable level of enantioselectivity.

Herein described is a sustainable system for hydrogenation that uses solar light as the ultimate source of energy. The system consists of two steps. Solar energy is captured and chemically stored in the first step; exposure of a solution of azaxanthone in ethanol to solar light causes an energy storing dimerization of the ketone to produce a sterically strained 1,2-diol. In the second step, the chemical energy stored in the vicinal diol is released and used for hydrogenation; the diol offers hydrogen onto alkenes and splits back to azaxanthone, which is easily recovered and reused repeatedly for capturing solar energy.

A mild and efficient protocol for the intramolecular aromatic C-H oxygenation of 2-biphenylcarboxylic acids has been achieved via iron photocatalysis. The 2-biphenylcarboxylic acids with a diverse array of substituents at both phenyl rings could furnish the oxygenation products in good to excellent yields. We speculate that the aryl carboxylate-iron(III) complexes should generate the aroyloxy radicals and iron(II) upon visible light irradiation.

p-Coumaric acid is a known inhibitor of tyrosinase, an enzyme involved in the initial steps of the melanin synthesis in human and other species. However, its low lipophilicity impairs its penetration through skin and efficacy as antimelanogenic agent indeed. Accordingly, this paper reports the assessment of several coumaric acid derivatives as tyrosinase inhibitors and antimelanogenic agents in in vitro, in silico and ex vivo assays. The compounds were designed with modifications in the aromatic and acid moieties of p-coumaric acid, being the coumarate esters the most promising derivatives. The compounds showed higher tyrosinase inhibitory activity (pIC(50), 3.7-4.2) than the parent acid, being compounds 1d, 1e and 1f the most potent inhibitors. Docking analysis showed that these esters are competitive inhibitors per se, and act independently of a redox mechanism as suggested by DPPH assays. Moreover, the esters showed efficacy in reducing the melanin deposition in human skin fragments at 0.1% concentration, especially compound le. In summary, there is an important equilibria between tyrosinase affinity and lipophilicity that must be considered to get effective antimelanogenic agents with adequate permeability in the skin.
