A new condensing agent, N,N prime -carbonyldi left bracket 1,2-benzisoxazol-3(2H)-one right bracket (6), was readily prepared by the reaction of 1,2-benzisoxazol-3-ol and trichloromethyl chloroformate in toluene. The condensing agent 6 was shown to be very useful for the preparation of amides, esters, and dipeptides under mild conditions. A successful polyamide synthesis by one-pot polycondensation of isophthalic acid with diamines using 6 is also described.
