Abstract

Enantiopure 1,4-benzodiazepin-4-one 1 and 1,4-benzodiazepin-6-ones 2 were reacted with hydrazonoyl chloride 8 in the presence of various basic agents. The diastereoselective 1,3-dipolar cycloaddition between the C=N double bond of 1 or 2 and the nitrilimine intermediate 9 gave the enantiopure [1,2,4]triazolo[4,3-a][1,4]benzo diazepinones 10-13.
