The title process has been accomplished by a three-step sequence involving protection of aldeh;de as the imine, in situ reduction of ketone with lithium tri-tert-butoxyaluminohydride, and regeneration of aldehyde on hydrolytic work-up. The preferential in situ ketalization or hydration of aldehydes
Few enantioselective reductions of ketones in inclusion complexes with cyclomaltoheptaose (p-cyclodextrin, /3CD) have been reported. Sakuraba et aE.l noted that treatment of such complexes with NaBH, in aqueous NaCl at 0" gave optically active alcohols, although the optical purity was not high. Dur
