Abstract: | Asymmetric reduction of aromatic ketones using chirally modified reagents prepared from sodium borohydride and optically active acids in the presence or absence of 1,2: 5,6-di-O-isopropylidene-α-d-glucofuranose produced the corresponding optically active alcohols with optical yields of 4 ~ 47%. The reagent prepared from sodium borohydride and 1 equivalent of l-malic acid in the presence of 2 equivalents of 1,2: 5,6-di-O-isopropylidene-α-d-gluco-furanose gave the highest yields. |
