vinyloxazaborolidines have been synthesized and subsequently hydrogenated using palladium on carbon under ambient conditions to produce, after oxidation of the boronate group, enantiomerically enriched secondary alcohols (up to 20% ee). Herein, the first example of asymmetric hydrogenation utilizing oxazaborolidines as chiralauxiliaries is reported.
