Development of a Scalable Route with Efficient Stereoisomer Control to YZJ-1139, an Orexin Receptor Antagonist
(R)-α-phenethyl was synthesized by the Robinson–Schöpf reaction and easily purified as hydrochloride. The single crystalX-ray study was used to confirm the stereo configuration of 13·HCl and 18·HCl. The protecting group could be easily removed by transfer hydrogenation, resulting in enantiomericallypure intermediate 3 as a d-tartarate. The overall yield for preparing YZJ-1139(1) was significantly increased
本文描述了食欲素受体拮抗剂 YZJ-1139( 1 ) 的合成和工艺开发。YZJ-1139( 1 ) 含有具有三个手性中心的氮杂双环去甲莨菪烷结构。原工艺通过色谱法可以得到高纯度的中间体或原料药,收率相对较低。为了尽早去除不需要的立体异构体,通过 Robinson-Schöpf 反应合成了具有 ( R )-α-苯乙基的中间体13 ,并易于纯化为盐酸盐。单晶 X 射线研究用于确认13·HCl和18·HCl的立体构型. 保护基可以很容易地通过转移氢化除去,得到对映体纯的中间体3,为d-酒石酸盐。制备 YZJ-1139( 1 )的总产率显着提高,这种具有成本效益的工艺在未来的商业生产中可能很有前景。
