โœฆ Synopsis


New Syntheses of Benzotriazepines by Non-Convenient Cyclization Reaction of N1,N3-Diarylamidrazones.

-The reaction of the N3-unsubstituted amidrazone (I) with formaldehyde gives the triazole (III). The corresponding N3-monosubstituted analogues (IV) yield the expected triazolines (V). Surprisingly, the amidrazones (VI) give the benzotriazepines (VII) under the same conditions.
