摘要
合成了标题化合物并测定了其晶体结构。该化合物的化学式为C26H25NO2S, Mr = 415.53。晶体为三斜晶系,P 空间群,晶胞参数为:a = 9.299(3), b = 10.134(3), c = 12.455(4) ? a = 98.457(5), b = 106.143(5), g = 103.843(5), V = 1065.7(6) 3, Z = 2, Dc = 1.295 g/cm3, F(000) = 440, m = 0.175 mm-1, R = 0.0406, wR = 0.1064。晶体结构显示,化合物中七员环呈类椅式构象,b-内酰胺环近似梯形。
The title compound was synthesized by [2+2] cycloaddition reaction and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to triclinic system, space group Pīwith a = 9.299(3), b = 10.134(3), c = 12.455(4) ? a = 98.457(5), b = 106.143(5), g = 103.843(5), V = 1065.7(6) 3, Z = 2, Dc = 1.295 g/cm3, F(000) = 440, m = 0.175 mm-1, R = 0.0406 and wR = 0.1064. X-ray structure analysis shows that the conformation of seven-membered ring is of chair-like, and the four-membered ring in the -lactam is approximately planar.
