The stereocenter in the intermediate alcohol (86% ee), created by enantioselective oxazaborolidinone-promoted aldol reaction, was transferred to the stereocenter in the cyclohexanone ring, necessary for (S)-ketamine, via allyl cyanate-to-isocyanate rearrangement. The second asymmetric synthesis of (S)-ketamine has been achieved (87% ee).
通过对映选择性恶唑硼烷酮促进的羟醛反应产生的中间体醇(86% ee)中的立体中心,通过氰酸烯丙酯到异氰酸酯重排转移到(S)-氯胺酮所需的环己酮环中的立体中心。已经实现了(S)-氯胺酮的第二次不对称合成(87% ee)。
