Details for the resolution of 1,2,3,5,6,10bβ-hexahydro-6α-phenylpyrrolo[2,1-α]isoquinoline (1), a potent antidepressant-like compound, into its enantiomers with di-p-toluoyltartaric acid (2) are reported. Enantio-merically-enriched R-(+)-2-phenylpyrrolidine was transformed into enantiomerically-enriched 1 to determine enantiomeric purity and absolute stereochemistry for the resolved amines 1. Thus, we
将1,2,3,5,6,10bβ-六氢-6α-苯基吡咯并[2,1-α]异喹啉(1)(一种有效的抗抑郁剂化合物)拆分为对映体与二-对甲苯甲酰基酒石酸的详细信息酸(2)的报道。对映merically富集的[R - (+) - 2-苯基吡咯烷转化为对映体富集1以确定用于解决胺对映体纯度和绝对立体化学1。因此,我们确定制备了对映体纯度≥99%的(+)-和(-)- 1样品,并且具有生物活性的(+)- 1具有6 S,10b R绝对配置。通过对由1或(-)- 1和(+)-莫氏酸(MTPA)形成的1:1非对映盐进行360-MHz 1 H nmr检查,确认对映体纯度≥99%。显示(+)- 3(100%op)的报告的最大旋光度(ref 8)对应于100%ee
