摘要：

The regio- and stereoselective ring opening of vinyl epoxides has been achieved by the use of Lewis acid, MgBr2, affording bromohydrins in excellent yield, which are readily transformed to azidoalcohol, a key intermediate of several classes of pyrrolizidine and indolizidine alkaloids. The scope and limitations of the reaction are discussed. (C) 2004 Elsevier Ltd. All rights reserved.
