A synthetic study of N-substituted (sarcosylamino)benzophenones 2 is described.The target molecules 2 were found to be reactive under neutral conditions, affording intramolecularly cyclized products.Compounds 6a and 13a were converted into pyrazinoquinazoline 9a and pyrazinoquinoline 18a, respectively.The new heterocycles were characterized, and possible mechanisms are proposed for their formation.
