摘要：

Asymmetric reductions of alpha-keto acetals using various oxazaborolidines and borane reagents as catalyst and the hydride source, respectively, were compared. The reduction catalyzed by Corey's CBS reagents with N-phenylamine-borane reagents provided alpha-hydroxy acetals with very high enantioselectivities for most aromatic analogues.
