The versatility of Kluyveromyces marxianus CBS 6556 growing cells in the enantioselective reduction of ketone functionalities to the corresponding alcohols was exploited. In particular, methyl ketones were reduced to (S)-alcohols with ees of up to 96%. Longer chain alkyl ketones afforded, under the same experimental condition, (R)-alcohols with an ee of up to 84%. Interestingly, carbon-carbon double and the triple bonds can also be reduced in the presence of Kluyveromyces marxianus CBS 6556 yeast. A cyclic ketone, such as 2-tetralone, was also quantitatively reduced to its corresponding (S)-alcohol with ee = 76%.
SYNTHESIS OF (2S,3R,7RS)-STEGOBINONE (2,3-DIHYDRO-2,3,5-TRIMETHYL-6-(1-METHYL-2-OXOBUTYL)-4H-PYRAN-4-ONE) AND ITS (2R,3S,7RS)-ISOMER. THE PHEROMONE OF THE DRUGSTORE BEETLE

Reaction of acetaldehyde with the trianion of 4,6-dimethylnonane-3,5,7-trione followed by acidification yielded a stereoisomeric mixture of stegobinone, the pheromone of Stegobium paniceum L.Acylation of the dianion derived from 4-methylheptane-3,5-dione
