There is provided a process for the hydrogenation of esters of alpha-substituted carboxylic acids which comprises reacting an ester of an alpha-substituted carboxylic acid with hydrogen in the presence of a catalyst under substantially homogeneous supercritical conditions. Preferably, the ester of an alpha-substituted carboxylic acids is an ester of formula (1): wherein: R1 and R2are each independently an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; and Y is a heteroatom or an optionally substituted heteroatom group. More preferably, the ester of an alpha-substituted is carboxylic acids is an ester of formula (2): wherein: R3 is an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; R4and R5 are each independently hydrogen, an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; Y is a heteroatom or an optionally substituted heteroatom group; Q is a functional group; and n 1. Most preferably, the ester of an alpha-substituted carboxylic acids is an ester of formula (3): wherein: R3 and R6 are each independently an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; R4 and R5 are each independently hydrogen, an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; Y is a heteroatom or an optionally substituted heteroatom group; and n 1.

Three acrylate comonomers, (S,S), (R,R) and racemic 1-methyl-2-hydroxypropyl acrylate (7a-c), were prepared from the corresponding isomers of 2,3-butanediol.The acrylates were copolymerized with ethylene dimethacrylate and N-acryloyl-(2S,4S)-4-(diphenylphosphino)-2-<(diphenylphosphino)methyl>pyrrolidine (8) to give cross-linked resins containing phosphinopyrrolidines and optically active alcohols.Polymers containing the 4,5-bis<(diphenylphosphino)methyl>-1,3-dioxolane unit (DIOP) were prepared by copolymerizing acrylates 7a-c with ethylene dimethacrylate and 2-p-styryl-4,5-bis<(tosyloxy)methyl>-1,3-dioxolane (1) and treating the polymers with an excess of sodium diphenylphosphide.Exchange of Rh(I) onto these polymers provided catalysts that hydrogenated 2-acetamidoacrylic acid in tetrahydrofuran.The enantiomeric excesses obtained with the polymer-bound catalysts varied with the structure of the pendent alcohol, suggesting the participation of the polymer-bound alcohol at the catalyst site to provide an alcohol-like environment.A difference in enantiomeric excess (ee) was noted when catalysts containing either R or S alcohols were used.

A series of chiral beta3-aminoxy acids or amides with various side chains have been synthesized via two different approaches. One is the Arndt-Eistert homologation approach, using chiral alpha-aminoxy acids as starting materials. The other approach, utilizing the enantioselective reduction of beta-keto esters catalyzed by baker’s yeast or chiral Ru(II) complexes, produces chiral beta3-aminoxy acids with nonproteinaceous side chains. The oligomers of beta3-aminoxy acids can be readily prepared using EDCI/HOAt as the coupling reagent.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 24621-61-2, you can also check out more blogs about24621-61-2

(Equation presented) Dibutylboron triflate/diisopropylethylamine mediated aldol-type cyclization provides an expedient route for the stereoselective synthesis of cyclic ethers in a single step. The method is highly efficient for the stereoselective synthesis of 4-cis-tetrahydropyranones. The reaction is proposed to proceed via an SN1-type mechanism through a chair-like transition state, in which both substituents occupy equatorial positions.
