摘　　要：A new series of 11-pyridyl substituted dibenzo-diazepin-l-one derivatives 1 was synthesized by a two step cyclocondensation reaction. All the compounds were characterized by IR, MS, and H NMR. And crystals of la and lb were obtained and determined by X-ray single-crystal diffraction. Crystal data of la： C48H52N607, monoclinic system, space group C2/c, a = 28.39（4）, b = 9.275（12）, c = 16.84（2） A, β = 104.98（3）°, V= 4284（10） A3, Z= 4, F（000） = 1752, Dc = 1.279 g/cm3, R = 0.0603, and wR = 0.1314. Crystal data of 1b： C24H21N30, monoclinic system, space group P21/c, a = 11.625（5）, b = 19.055（9）, c = 8.741（4） A, fl = 95.547（6）°, V= 1927.2（15） A3, Z = 4, F（000） = 776, Dc = 1.266 g/cm3, R = 0.0494, and wR = 0.1287.A new series of 11-pyridyl substituted dibenzo-diazepin-l-one derivatives 1 was synthesized by a two step cyclocondensation reaction.
