Abstract
2,3-Epoxyalcohols react with diethylaluminium azide under mild conditi ons to give 3-azido-1,2-diols resulting from the regio- and stereosele ctive attack of the nucleophile at the epoxide C-3. The high regiosele ctivity (>25:1) observed with both cis and trans substituted epoxides is not affected by bulky substituents at C-3. The method has been succ essfully applied also to the synthesis of diaminodiol dipeptide isoste res, (C) 1998 Elsevier Science Ltd. All rights reserved.
