Abstract
Abstract Treatment of the imide derivatives 1 and 3 readily obtainable from 2-azidobenzoyl chloride and the corresponding amide derivatives with triphenylphosphine or tributylphosphine in xylene at room temperature gave quinazolinones 2 and 4 in excellent yields via the Staudinger reaction, followed by the intramolecular aza-Wittig reaction.
