Alkyl azides were found to undergo intramolecular cycloadditions with certain 1,3-dienes to provide 2,3,5,7a-tetrahydro-1H-pyrrolizines and 3,5,6,7,8,8a-hexahydroindolizines in one operation (e.g., 12 -> 13 and 17 -> 18).The presence of an electron-donati

Cyclization of heterosubstituted ο-azidodienes 11 provides fused bicyclic 3-pyrrolines 12 in one operation.These pyrrolines are potentially useful intermediates for natural products synthesis, as illustrated by further functionalization.
