The highly diastereoselective addition of allylzinc bromide to imines derived from (R)-phenylglycine amide is reported. Homoallylamines with high enantiomeric purity are obtained from the adducts in three steps on removal of the chiral auxiliary by means of a nonreductive protocol. Removal of the auxiliary by hydrogenation leads to the saturated amines, also in high enantiomeric purity. [reaction: see
据报道,烯丙基溴化锌以高度非对映选择性加成到衍生自 (R)-苯基甘氨酸酰胺的亚胺中。具有高对映体纯度的高烯丙基胺通过非还原性方案在去除手性助剂的三个步骤中从加合物中获得。通过氢化除去助剂产生饱和胺,也具有高对映体纯度。[反应:见正文]
