Meijere reaction between an unsaturated Grignard reagent and a chiral amide takes place with a high trans stereoselectivity and provides a convenient access to non-racemic trans cyclopropylamines. These compounds are transformed in four steps into the corresponding N-protected β,γ-methano-GABA derivatives, which are obtained for the first time in enantiomerically pure form. The corresponding transformations
不饱和格氏试剂与手性酰胺之间的Kulinkovich-de Meijere反应具有很高的反式立体选择性,可方便地获得非外消旋的反式环丙胺。这些化合物经四个步骤转化为相应的N-保护的β,γ-甲基-GABA衍生物,它们首次以对映体纯形式获得。还描述了顺式环丙胺加合物的相应转化。
