Single-crystal X-ray analyses have defined the structures and solid-state conformations of (±)-N-benzoyl-3-methylaminocycloheptanone [(±)-]and (+)-N-benzoyl-4-methylaminocycloheptanone [(±)]. Resolution of (±)-[4- methylaminocycloheptanone α 1-hydroxytropane]to yield the (+)-enantiomer. Identical in all respects with the free base from natural (+)-physoperuvine, was achieved via the di-p-toluoyl-(+)-tartrate
单晶X射线分析确定了(±)-N-苯甲酰基-3-甲基氨基环庚酮[(±)- ]和(+)- N-苯甲酰基-4-甲基氨基环庚酮[(±)]。拆分(±)-[4-甲基氨基环庚酮α1-羟基托烷]以产生(+)-对映体。在所有方面,通过二-对甲苯甲酰基-(+)-酒石酸盐可实现与天然(+)-紫杉烷的游离碱相同。
