Complementary new routes to both enantiomers of N-protected pipecolic acid and the corresponding 4,5-dihydroxylated derivatives are developed, which involve stereo-divergent allylation of a chiral N-allylimine and ring-closing metathesis as key steps.
已开发出同时获得N-保护的胡椒酸对映异构体和相应的4,5-二羟基化衍生物的互补新途径,其中涉及手性N-烯丙胺的立体发散烯丙基化和闭环易位作为关键步骤。
