Reductions of keto esters with Baker's yeast in organic solvents - a comparison with the results in water: Reductions of keto esters with Baker's yeast in organic solvents - a comparison with the results in water. Rotthaus, Olaf; Krueger, Doris; Demuth, Martin; Schaffner, Kurt ( Max-Planck-Inst. Strahlenchemie, Muelheim an der Ruhr D-45470, Germany).In this study，4949-44-4 is also used. Tetrahedron, 53(3), 935-938 (English) 1997 Elsevier. CODEN: TETRAB. ISSN: 0040-4020. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 22 The enantiomeric excess in redns. of keto esters with Baker's yeast (Saccharomyces cerevisiae) can conveniently be altered in org. solvents such as Et2O, PhMe, hexane and EtOAc, when compared to corresponding transformations in water. Thus, while yields were generally lowest in EtOAc, MeCO(CH2)nCO2Et (n = 0, 1) gave nearly quant. yields of (S)-HOCHMe(CH2)nCO2Et in ￡100% e.e. in the other 4 solvents. RCOCH2CO2Et (I; R = ClCH2) gave slightly lower yields of the corresponding (R)-HOCHRCH2CO2Et in all solvents except H2O. The major product isomer and stereoselectivity from I (R= Et, Pr) varied with the solvent. .

DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Thiophenecarboxylates (I; R = Me, Et; R1 = Me, Pr; R2 = cyano, EtO2C) are prepd. by reaction of an alkanoylacetate with a malonic acid deriv. and S, followed by cyclization of the reaction product. Thus, reaction of 116 parts MeCOCH2CO2Me with 66 parts CH2(CN)2 and 32 parts S 3 hr at room temp. in presence of Et3N, followed by 3 hr at 40.degree., gives 156 parts I (R = R1 = Me, R2 = cyano). .
