Title: Synthesis of alexine-like compounds from chiral five-membered endocyclic enecarbamates
Author: Valle, MS

Abstract: Stereoselective syntheses of enantiomerically enriched trihydroxy pyrrolizidine and indolizidines were accomplished from a common chiral endocyclic enecarbamate. The synthetic strategy features an efficient [2+2] cycloaddition of ketenes to the endocyclic enecarbamate and a highly regioselective Baeyer-Villiger oxidation of the intermediate azabicyclic-cyclobutanones. These new heterocycles are compounds structurally related to the alexines. (c) 2008 Elsevier Ltd. All rights reserved.
