Asymmetric total synthesis of (S)-vigabatrin. Author is Gnamm, Christian; Franck, Geraldine; Miller, Nicole; Stork, Timon; Broedner, Kerstin; Helmchen, Guenter.

Iridium-catalyzed aminations of allylic carbonates containing a variety of O-functional groups have been explored. High degrees of regio- as well as enantioselectivity were achieved with diacylamides under salt-free conditions and with arylamines. The results allowed the antiepilepsy drug (S)-vigabatrin to be prepared via a very short route.

A novel Pd0-catalyzed asym. [4+3] annulation reaction of two readily accessible starting materials was developed for building seven-membered heterocyclic architectures. The potential [3+2] side pathway could be suppressed though fine tuning of the conditions. A broad scope of cycloaddition donors and acceptors participated in the transformation with excellent chemo-, regio-, diastereo- and enantioselectivtities, leading to valuable tetrahydroazepines, e.g., I and benzo[b]oxepines, e.g., II.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Assessing the Activity of Lewis Bases Organocatalysts in Halonium-Induced Carbocyclization Reactions, published in 2018-06-30, which mentions a compound: 415918-91-1, mainly applied to Lewis base organocatalyst halonium carbocyclization alkynylstyrene cinnamylaniline; phosphine phosphorus chalcogenide halosuccinimide catalyzed carbocyclization alkynylstyrene; halonium induced carbocyclization alkynylstyrene cinnamylaniline, Synthetic Route of C36H30NO2P.

Lewis bases were evaluated as catalysts for halocarbocyclization reactions of alkynylstyrenes and a cinnamylaniline derivative Phosphines and phosphorus chalcogenides exhibited high activity for the conversion of alkynylstyrenes in the presence of N-halosuccinimides with up to a 30-fold increase of the initial reaction rate with respect to the background reaction. Phosphorus sulfides and selenides showed the best catalytic activity for the iodocarbocyclization of a cinnamylaniline derivative in the presence of diiodohydantoin. An asym. variant of the iodocarbocyclization reaction of an alkynylstyrene using a chiral phosphorus selenide resulted in a modest enantioselectivity.

Computed Properties of C36H30NO2P. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, is researched, Molecular C36H30NO2P, CAS is 415918-91-1, about Enantioselective Syntheses of Strychnos and Chelidonium Alkaloids through Regio- and Stereocontrolled Cooperative Catalysis. Author is Hutchings-Goetz, Luke S.; Yang, Chao; Fyfe, James W. B.; Snaddon, Thomas N..

We describe enantioselective syntheses of strychnos and chelidonium alkaloids. In the first case, indole acetic acid esters were established as excellent partner nucleophiles for enantioselective cooperative isothiourea/Pd catalyzed α-alkylation. This provides products containing indole-bearing stereocenters in high yield and with excellent levels of enantioinduction in a manner that is notably independent of the N-substituent. This led to concise syntheses of (-)-akuammicine and (-)-strychnine (I and II, resp.). In the second case, the poor performance of ortho-substituted cinnamyl electrophiles in the enantioselective cooperative isothiourea/Ir catalyzed α-alkylation was overcome by appropriate substituent choice, leading to enantioselective syntheses of (+)-chelidonine, (+)-norchelidonine, and (+)-chelamine (III – V, resp.).

Recommanded Product: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, is researched, Molecular C36H30NO2P, CAS is 415918-91-1, about Palladium-Catalyzed Enantioselective Cycloadditions of Aliphatic 1,4-Dipoles: Access to Chiral Cyclohexanes and Spiro [2.4] heptanes. Author is Trost, Barry M.; Jiao, Zhiwei; Liu, Ying; Min, Chang; Hung, Chao-I. Joey.

Design and exploration of new intermediates for chemo-, regio-, and stereoselective cycloadditions remain a formidable challenge in modern organic synthesis. Compared to the well-developed 1,3-dipolar cycloadditions, Pd-catalyzed 1,4-dipolar cycloadditions are generally limited to specialized substrates due to the inherent nature of the thermodynamically driven intramol. transformations and undesired isomerizations. Herein, we demonstrate the use of ligated palladium catalysts to control and modulate the intermol. reactivity of aliphatic 1,4-dipoles, enabling two distinctive cycloaddition pathways with a broad scope of acceptors. This atom-economic process also features an eco-friendly in situ deprotonation strategy to generate the corresponding active palladium-mediated dipoles. Overall, a diverse array of chiral 6-membered rings and spiro [2.4] heptanes were prepared in high yield and selectivity. In addition, an unexpected property of cyano-stabilized carbanions was discovered and investigated, which can be useful in designing and predicting future transformations.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 415918-91-1, is researched, SMILESS is C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7, Molecular C36H30NO2PJournal, Article, Angewandte Chemie, International Edition called The Supramolecular Balance for Transition-Metal Complexes: Assessment of Noncovalent Interactions in Phosphoramidite Palladium Complexes, Author is Hartmann, Evelyn; Gschwind, Ruth M., the main research direction is noncovalent interaction palladium phosphoramidite NMR.SDS of cas: 415918-91-1.

The authors have presented a method to determine exptl. and quant. the contribution of noncovalent interactions within transition-metal complexes. In this general approach the ΔΔG value of two complex equilibrium is used as a measure for the deviating noncovalent interactions within the two hetero-complexes. The two equilibrium are energetically linked by the combination of one enantiopure ligand with two enantiomeric ligands, leading to identical or enantiomeric homo-complexes. This allows for the separation of supramol. interactions from stereoelectronic and electrostatic properties provided that the general complex structure is retained. Since this method uses deviating intra-complex interactions within two hetero-complexes, solvation effects of the interacting functional groups are of minor importance. The applicability of this approach was proven with phosphoramidite palladium complexes. The mutual exchange of the CH3 and the Ph groups from one ligand to its enantiomer is directly reflected in the NMR data. The exptl. determined ΔΔG value is of the right order of magnitude for the observed changes in the interaction pattern. This example proves for the first time that the catalytically highly important class of phosphoramidite ligands show a pseudo-bidentate character in solution and that modulations in the extended planar CH-π and π-π interaction interfaces cause significant energetic differences.

As far as I know, this compound(415918-91-1)SDS of cas: 415918-91-1 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
