Biomimetic asymmetric reduction of 2-functionalized quinolines has been successfully developed with the chiral and regenerable NAD(P)H model CYNAM in the presence of transfer catalyst simple achiral phosphoric acids, providing the chiral 2-functionalized tetrahydroquinolines with up to 99% ee. Using this methodology as a key step, a chiral and potent opioid analgesic containing a 1,2,3,4-tetrahydroquinoline
在转移催化剂简单的非手性磷酸存在下,利用手性和可再生的 NAD(P)H 模型 CYNAM 成功开发了 2-官能化喹啉的仿生不对称还原,提供了高达 99% ee 的手性 2-官能化四氢喹啉。使用该方法作为关键步骤,合成了一种含有 1,2,3,4-四氢喹啉基序的手性强效阿片类镇痛剂,总收率高。
