Asymmetric reduction of carbonyl compounds by yeast

Asymmetric reduction of carbonyl compounds by yeast. II. Preparation of optically active .alpha.- and .beta.-hydroxy carboxylic acid derivatives. Deol, Badan S.; Ridley, Damon D.; Simpson, Gregory W. (Dep. Biochem., Univ. Sydney, Sydney, Aust.). Aust. J. Chem., 29(11), 2459-67 (English) 1976. CODEN: AJCHAS. DOCUMENT TYPE: Journal CA Section: 16 (Fermentations) Some .alpha.- and .beta.-keto esters and amides are readily reduced by an actively fermenting mutant of Saccharomyces cerevisiae and produce optically active .alpha.- and .beta.-hydroxy esters and amides in moderate yields. Typically, methyl-2-oxo-2-phenylacetate [15206-55-0] gave methyl (R)-(-)-2-hydroxy-2-phenylacetate [20698-91-3]; 2-oxo-2-phenylacetamide [7505-92-2] gave (R)-(-)-2-hydroxy-2-phenylacetamide [24008-62-6]; ethyl benzoylacetate [94-02-0] gave ethyl (S)-(-)-3-hydroxy-3-phenylpropionate [33401-74-0], and ethyl 2-oxocylohexanecarboxylate [1655-07-8] gave ethyl (1R,2S)-(+)-2-hydroxycyclohexanecarboxylate [61586-78-5]. In each case, the product obtained was optically pure. However, the redn. 617-35-6 is just another one chemical used in this study. of ethyl pyruvate [617-35-6] to ethyl lactate [97-64-3] produced partially racemized products. .
