The reactivity of imide carbonyl groups in the intramolecular aza-Wittig reaction. An efficient route to iminolactam derivatives
Abstract
Treatment of N-(ω-azidoalkyl)imides with triphenylphosphine in toluene or xylene under reflux gave the corresponding iminolactam derivatives in good yields via the Staudinger reaction followed by the intramolecular aza-Wittig reaction.
