An effective protocol for the synthesis of potentially bio- active benzo(e)chromeno(6,5-b)(1,4)diazepine-3,8(7H,13H)-dione and dibenzo(b,e)(1,4)diazepin-11(10H)-one derivatives in good to excellent yields has been achieved by CuI/L-Proline catalyzed cou- pling reaction as the key step. The methodology offers clean reac- tion conditions and easy isolation of the products in 61-92% yields.
