Tanasova, Marina; Anyika, Mercy; Borhan, Babak published an article in 2015, the title of the article was Sensing Remote Chirality: Stereochemical Determination of β-, γ-, and δ-Chiral Carboxylic Acids.Name: (R)-Methyl 3-hydroxybutanoate And the article contains the following content:

Determining the absolute stereochem. of small mols. bearing remote nonfunctionalizable stereocenters is a challenging task. Presented is a solution in which appropriately substituted bis(porphyrin) tweezers are used. Complexation of a suitably derivatized β-, γ-, or δ-chiral carboxylic acid to the tweezer induces a predictable helicity of the bis(porphyrin), which is detected as a bisignate Cotton Effect (ECCD). The sign of the ECCD curve is correlated with the absolute stereochem. of the substrate based on the derived working mnemonics in a predictable manner. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Name: (R)-Methyl 3-hydroxybutanoate

And the article contained the following:

The 2-Acetyl-gamma-butyrolactone (2-AgBL) was characterized by quantum computational studies with DFT approaches. A relaxed PES scan was employed in this study to determine the order of stability conformations in the vacuum and aqueous phases, and then dimerization for the stable conformer was done in water phase. The mol. structure and geometries of monomer, as well as a dimer for the stable conformer were obtained, and they were confirmed by theor. IR spectroscopy. The ELF, LOL, QTAIM and NCI-RDG techniques are utilized to explore weak donor strong acceptor (C-H···O=C) type hydrogen bonds and other non-covalent interactions in dimer. The stability of compound was internally assessed by the NBO anal. in different mediums. On the gas and solvent phases: UV-Vis absorptions, Mol. Electrostatic potentials, global reactive parameters (FMOs), and Fukui Functions anal. were also performed in this study. A Solute-solvent interaction center was found in the water solvent for 2-AgBL. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Computed Properties of 517-23-7

Peng, Juan; Wang, Xuefeng; Zhang, Xiaoming; Bai, Shiyang; Zhao, Yaopeng; Li, Can; Yang, Qihua published an article in 2015, the title of the article was Asymmetric hydrogenation by RuCl2(R-Binap)(dmf)n encapsulated in silica-based nanoreactors.Electric Literature of 3976-69-0 And the article contains the following content:

The Noyori catalyst RuCl2(R-Binap)(dmf)n has been successfully encapsulated in C-FDU-12 by using the active chlorosilane Ph2Cl2Si as the silylating agent. 31P-NMR results show that there is no strong interaction between the mol. catalyst and the solid support, thus the encapsulated mol. catalyst could move freely in the nanoreactor during the catalytic process. The solid catalyst exhibits high activity and enantioselectivity for the asym. hydrogenation of a series of β-keto esters due to the preserved intrinsic properties of RuCl2(R-Binap)(dmf)n encapsulated in the nanoreactor. The solid catalyst could be recycled by simple filtration and be reused at least four times. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Electric Literature of 3976-69-0

Wang, Xu; Lu, Sheng-mei; Li, Jun; Liu, Yan; Li, Can published an article in 2015, the title of the article was Conjugated microporous polymers with chiral BINAP ligand built-in as efficient catalysts for asymmetric hydrogenation.Formula: C5H10O3 And the article contains the following content:

A series of chiral conjugated microporous polymers (CMPs) based on the chiral (R)-BINAP ligand (BINAP-CMPs) were synthesized with tunable BET surface areas. These solid catalysts show high activities and enantioselectivities for the asym. hydrogenation of β-keto esters after coordination with ruthenium species. Moreover, CMPs can realize spatial isolation. Through preventing the formation of dimers and trimers, BINAP-CMPs show much higher activity than BINAP for the Ir-catalyzed asym. hydrogenation of quinaldine.
