Abstract
Abstract The performance of several 1,3,2-oxazaborolidines as chiral catalysts in the reduction of acetophenone has been compared, to gain insight into the more relevant structural factors as far as yield and enantioselectivity are concerned. B-Alkyl-4,5,5-triphenyl-1,3,2-oxazaborolidines have emerged as effective catalysts for this reaction when nitrogen is not substituted. The origin of the enantioselectivity for this kind of catalysts is discussed.
