Synthesis of 5-hydroxy-Δ1-pyrrolines conjugated with aryl substituents has been effected via the rearrangement of O-vinylketoximes, having only one C–H bond adjacent to the oxime function and readily prepared by addition of sec-alkyl aryl ketoximes to acetylene. The target compounds were obtained in 80–86% yields (based on the O-vinylketoximes).
