Syntheses and Crystal Structures of Pyridyl Substituted Dibenzo[b,e]-[1,4]diazepin-1-one Derivatives
A new series °f 11-pyridyl substituted dibenz°-diazepin-1-°ne derivatives 1 was synthesized by a tw° step cycl°c°ndensati°n reacti°n. All the c°mp°unds were characterized by IR,MS, and 1H NMR. And crystals °f 1a and 1b were °btained and determined by X-ray single-crystal diffracti°n. Crystal data °f 1a: C48H52N6O7, m°n°clinic system, space gr°up 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 °f 1b: C24H21N3 O, m°n°clinic system, space gr°up P21/c,a = 11.625(5), b = 19.055(9), c = 8.741(4) A, β = 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. 相似文献
