The catalytic asymmetric reduction of different ketones1 with transient hypervalent silicon hydrides is described. Trialkoxysilanes, upon activation by a small amount of a chiral nucleophile, underwent addition to the carbonyl group, forming the corresponding silyl protected alcohols, which were cleaved during the workup to give the enantiomerically enriched product alcohols. A brief screening of the reaction parameters and the results are summarized below.
