3- -propionic acid, methyl ester

In a more detailed study, the same esterase P. fluorescens) was again subjected to mutagenesis using the same mutator strain, but also by saturation mutagenesis at selected positions 133a). In addition to 3-phenylbutyric acid ethyl ester (27), 3-bromo-2-methyl-propionic acid methyl ester rac-31) was chosen for the hydrolytic kinetic resolution, with the WT PFE showing an E factor of 12 in favor of the (5)-32.

The possibility of the triazene linking system for the ester-enolate imine condensation was initially investigated on model compounds 110 and 111 (Scheme 35). Dibenzyltriazene 110 was used as a model compound for monobactam derivatives and prepared by diazotization of hippuric acid methyl ester. Dibenzyltriazene 111 was used as a model compound for 3-phenyl-substituted azetidin-2-ones and prepared by diazotization of 2-(4-aminophenyl)-propionic acid methyl ester and conversion with dibenzylamine in 64% overall yield. The low yields of /V-unsub-stituted lactams, during the model studies, hint at a problematic transfer to solid support. [Pg.290]

Xia et al. [63] developed new acyl AAS having the general structure a-amino-(Ai-acyl)-P-alkoxypropionate. The structure-function relationship of the anionic amino-alkoxypropionates was evaluated, with an emphasis on their antimicrobial properties. The anionic amino-alkoxypropionate was synthesized, starting from propionic acid methyl ester, through alkoxylation with fatty alcohol, bromination, saponification, amidation, acylation with R OCl (acyl chloride), and saponification to obtain the final product. For the detailed procedure, see Xia et al. [63]. [Pg.95]
