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.
