Selective syntheses of triazino [4,3-a]quinazolines 3ae and their isomeric triazino [3,2-b]quinazolines 4ae by cyclization of the appropriate a-keto acid hydrazones 2a-e under different reaction conditions are described. The angular triazinoquinazolines 3a-e were readily rearranged to the correspond
