โœฆ Synopsis

Kinetic resolution of sec-alcohols was performed by using axially chiral twisted amides, 4-(S)-alkyl 3-pivaloyl-l,3-thiazolidine-2-thiones (lb-ld and 2). The (S)-pivalates were selectively produced under neutral conditions; in contrast, the (R)-isomers were produced as major products in the presence of MeMgBr.

Dynamic kinetic resolution of N-acylhemiaminals was performed by enantioselective acylation of the hydroxy groups with chiral twisted amides. The stereoselectivity was reversed in the presence of 4-DMAP. The absolute configuration of the products was determined based on the sign of CD Cotton effects

Horse liver alcohol dehydrogenase-catalyzed oxidoraducticn was useful to resolve racemic lformyl-Z-methyl derivatiws of tricarbonyl(cyclopentadienyl)manganese and (benzene)tricarbonylchromium and racemic 1-hydroxyethylferrocene, ruthenocene and osmocme.
