Novel Method for the Synthesis of [1,2,4]Triazino[4,3‐c]quinazoline System
摘要:
4-Hydrazinoquinazoline was found to form new 2-(3,4-dihydro-3oxo-2H[1,2,4]triazino[4,3-c]quinazolin-4-yl)acetic acid with maleic anhydride in on-step sequence. Proposed heterocyclization includes, probably, acylation reaction followed by intramolecular uncleophilic addition.
