2-Benzoylbenzoyl azides undergo facile cyclization under acidic conditions to give substituted dibenzo[b,f][1,5]-diazocines in good yields. This approach shortens the synthetic steps toward these compounds as compared with conventional methods. The mechanism of the diazocine synthesis is assumed to proceed by an unprecedented intermolecular [2 + 2] cyclization.
2-苯甲酰基苯甲酰基叠氮化物在酸性条件下容易环化,以高收率得到取代的二苯并[ b,f ] [1,5]-重氮电影。与常规方法相比,该方法缩短了合成这些化合物的步骤。假定重氮合成的机理是通过前所未有的分子间[2 + 2]环化进行的。
