Baker's yeast mediated biohydrogenation of unsaturated compounds containing a methylene group: enantioselective preparation of 2-methyl alkanols from 2-substituted acrolein acetals
摘要:
The baker's yeast mediated biohydrogenation of unsaturated compounds containing a methylene group may constitute an enantioselective biocatalytic approach to the preparation of 2-methyl-1-alkanols, as exemplified by the reduction of the compounds 8a-d to 90-98% enantiomerically pure alcohols 2a-d.

A nickel-catalyzed hydrovinylation of α-ketal derivatives of vinylarenes has been developed, providing a new method for preparing functional olefins with a quarternary carbon center in high yields and selectivities.
