Reaction of anthranilic acid 2-N-phenylhydrazide with cyclic anhydrides
摘要:
In the reaction with cyclic anhydrides the anthranilic acid 2-N-phenylhydrazide depending on conditions yielded either anthranilic acid 2-N-acyl-2-N'-phenylhydrazides, 2-R-3-anilinoquinazolin-4(3H)-ones, or derivatives of 1-phenylpyridazino[3,2-b]quinazoline-2,10-dione.
