The synthesis, absolute configuration, chiroptical properties and hydrogen bonding of the helical-chiral title compound 1 are reported, which is the first strained [2.2]phane that has an unsubstituted nitrogen in the bridge; an X-ray structure analysis shows 1 to crystallise spontaneously enantiomerically pure, and the presence of the sulfure atom allowed the determination of the absolute configuration
报道了螺旋-手性标题化合物1的合成,绝对构型,手性和氢键,这是第一个在桥中具有未取代氮的应变[2.2] phane。X射线结构分析显示1可以自发地结晶为纯对映体,并且
硫原子的存在使确定(-)-对映体的绝对构型得以确定为左旋(M)螺旋。
