Özet

We hereby report a new synthetic methodology for construction of the 1,3,4,5-tetrahydro-2H-1,3-benzodiazepin-2-one skeleton. 2-(2-Carboxyethyl)benzoic acid was converted into the corresponding bis(acyl azide). Curtius rearrangement of the diazide followed by reaction with alcohols provided diurethane derivatives. Ring-closure reaction of the diurethanes with base resulted in formation of the 1,3-benzodiazepin-2-one skeleton.
