The present invention is directed to a simple and economical process for the preparation of 8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-benzo[d]azepine via novel intermediates and a highly selective asymmetric synthesis leading to enantiopure (R)-8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-benzo[d] azepine or its (S)-enantiomer, in order to avoid or overcome chemical optical resolution.
本发明涉及一种简单经济的方法,通过新颖的中间体和高度选择性的不对称合成,制备8-氯-1-甲基-2,3,4,5-四氢-1H-苯并[d]氮杂环己烷,从而得到对映纯度为(R)-8-氯-1-甲基-2,3,4,5-四氢-1H-苯并[d]氮杂环己烷或其(S)-对映异构体,以避免或克服化学光学分辨。
