Catalytic asymmetric deprotonation-aldehyde trapping-ring expansion from a 5- to a 6-ring delivers a concise route to each stereoisomer of β-hydroxy piperidines starting from N-Boc pyrrolidine. The methodology is utilized in a 5-step catalytic asymmetric synthesis of the neorokinin-1 receptor antagonist, (+)-L-733,060.
从N -Boc吡咯烷开始,催化的不对称去质子醛捕获环从5个环扩展为6个环,为向β-羟基哌啶的每个立体异构体提供了一条简洁的途径。该方法用于新激酶1受体拮抗剂(+)-L-733,060的5步催化不对称合成。
