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 pyrazino<2,1-b>quinazoline 9a and pyrazino<2,3-b>quinoline 18a, respectively.The new heterocycles were characterized, and possible mechanisms are proposed for their formation.
