Allylmetal reagents add to the imine derived from 2-pyridine carboxaldehyde and methyl (S)-valinate or to preformed imine-metal salt complexes to give mainly the S,S- or the R,S-secondary homoallylic amine, depending on the nature of the allylmetal reagent. Both the (S)- and (R)-1-(2-pyridyl)-3-butenamine were prepared with high enantiomeric purity by removal of the auxiliary group.
烯丙基金属试剂会添加到由2-吡啶羧醛和(S)-缬氨酸甲酯衍生的亚胺中,或添加到预先形成的亚胺-金属盐络合物中,从而主要生成S,S-或R,S-仲均烯丙基胺,具体取决于烯丙基金属试剂。通过除去辅助基团,以高对映体纯度制备(S)-和(R)-1-(2-吡啶基)-3-丁烯胺。
