  摘要：

  An efficient synthesis of optically active beta-azido alcohols from their ketoazides by a one-pot reduction and an in situ lipase resolution protocol is described. The synthetic utility of this procedure has been illustrated by its application in the practical synthesis of both enantiomers of the natural hydroxyamides, tembamide, aegeline and the cardiac drug denopamine, with high enantioselectivities.

  A process for preparing optically active secondary alcohols of the general formula (3), [wherein R 1 is linear lower alkyl, an aromatic ring group, or the like; A is CH 2 NR 2 R 3 or the like; n is an integer of 0 to 2; and * represents an asymmetric carbon atom] by asymmetrically hydrogenating a ketone compound of the general formula (1) having nitrogenous or oxygen functional group at any of the a-, &bgr;- and &ggr;-positions, with selectivity among functional groups by the use of a ruthenium/optically active bidentate phosphine/diamine complex as the catalyst in the presence of hydrogen alone or together with a base. The optically active secondary alcohols obtained by the process are useful as drugs and intermediates for the preparation of drugs.
