A new synthesis of imidazolinones and quinazolinones by intramolecularaza-Wittigreaction is described. Readily available azido substituted imides , , , and reacted with triphenylphosphine or tributylphosphine to afford the corresponding imidazolinones , and quinazolinones , via the Staudinger reaction, followed by an intramolecularaza-Wittigreaction.
