C. Fuganti et al., Baker's yeast mediated enantioselective synthesis of the bisabolane sesquiterpenes curcumene, turmerone, dehydrocurcumene and nuciferal, J CHEM S P1, (3), 1999, pp. 279-282
Fermenting baker's yeast converts the allylic alcohol 6 into enantiomerical
ly pure (S)-(+)-3-(p-tolyl)butan-1-ol 7 which is a useful chiral building b
lock for the synthesis of bisabolane sesquiterpenes. The versatility of thi
s approach is shown in the preparation of (S)-(+)-curcumene, (S)-(+)-turmer
one, (S)-(+)-dehydrocurcumene and (E,S)-(+)-nuciferal.
