✦ Synopsis


The mode of reduction through fermenting baker's yeast and Hansenula anomala CBS 110 of 4-phenylbut-3-en-2-ones 7-9 has been studied. The ratio between saturated ketones 1-3, saturated carbinols 4-6 and starting materials 7-9 depends upon the microorganism used and the incubation period. When using as substrate ketone 7, obtained from natural precursors and baker's yeast as reducing agent, up to 80.5% of natural raspberry ketone 1 is obtained.

KEY WORDS 4-phenylbutan-2-one; natural raspberry ketone; 4-phenylbut-3-en-2-one; microbial reduction; deuterium labelling experiments
