A chiral Lewis base organocatalyzed enantioselective hydrosilylation of alpha-keto ketimines was investigated. The reactions afforded various enantioenriched alpha-amino ketones with good yields(up to 95%) in moderate to good enantioselectivities(up to 98% e. e.). Furthermore, one of the products was reduced to a chiral 1,2-amino alcohol. Following cyclization of it with triphosgene generated a cannabinoid receptor 1(CB1) inhibitor with good diastereoselectivity.
