Abstract

Fused pyrrole derivatives R 0160A Novel [3 + 2] Dipolar Cycloaddition Approach to Hexahydrobenzofuro[3,2-b]pyrroles. -The ring system is prepared by stereoselective intramolecular cycloaddition of azomethine ylides, generated from 2-vinyloxybenzaldehydes. The method is also applicable to secondary amino acids providing indolizidines of type (V) under similar conditions. -(KIM*, I.; NA, H.-K.; KIM, K. R.; KIM, S. G.; LEE, G. H.;
