摘要
A new and efficient one-pot synthesis of [1,2,3]triazolo[1,5-a][1,4] benzodiazepin-6(4H)-ones is described starting from readily available anthranilic acids. A small array of the title compounds were assembled via a four-step sequence involving diazotisation, azide addition followed by amide bond formation employing polymer supported carbodiimide and subsequent 1,3-dipolar cycloaddition reaction.
