Synthesis of 1,5‐Benzodiazepine Derivatives Containing 1,2,3‐Triazole Moiety via 1,3‐Dipolar Cycloaddition Reaction

A series of 1,5‐benzodiazepine derivatives were synthesized by the reaction of 1,5‐benzodiazepine containing 1,2,3‐triazole moiety with benzohydroximinoyl chlorides at room temperature. The structural identities of these novel compounds were confirmed on the basis of IR, 1H NMR, mass spectral and elemental analysis data, and by X‐ray crystallographic analysis of a typical example of the new class of 1,5‐benzodiazepine analogs.
