24–27 derived from L-amino acids have been found to proceed stereoselectively, yielding tricyclic fused pyrrolidines and piperidines. Further manipulation led to chiral hydroxymethyl-substituted fused piperidines 33–35 and to 3-amino-4-(1-hydroxypropyl)-2-mercaptomethyl-N-methylpiperidine (36). The structures and stereochemistries of the fused systems, as well as those of the piperidines, have been established
已发现衍生自 L-氨基酸的肟 1-3 和 24-27 的分子内腈氧化物烯烃环加成 (INOC) 反应立体选择性地进行,产生三环稠合吡咯烷和哌啶。进一步的操作导致手性羟甲基取代的稠合哌啶 33-35 和 3-氨基-4-(1-羟丙基)-2-巯基甲基-N-甲基哌啶(36)。已通过 NMR 确定了稠合系统以及哌啶的结构和立体化学。
