other organometallic reagents such as Mg. Al, Cu, Tl, and B derivatives reacted at the nitrogen atom. Use of the (S)-amine as a chiral auxiliary of 2 created the R chirality at the imino carbon. Very high chiral Induction was realized In the reaction of prenylzinc reagent wlih α-imino 8-(-)phenylmenthyl ester (10). The reaction of 2 with heteroatom substituted allylic organometalic compounds (15) gave
苄基锌试剂仅与α-亚氨基酯(2)在α-碳上反应,其他有机金属试剂(如Mg)也可与之反应。Al,Cu,Tl和B衍生物在氮原子上反应。(S)-胺作为2的手性助剂的使用在亚氨基碳上产生R手性。在异戊二烯锌试剂与α-亚氨基8-(-)苯基薄荷基酯(10)的反应中实现了非常高的手性诱导。2与杂原子取代的烯丙基有机金属化合物(15)反应,得到相应的α-异位取代的氨基酸衍生物(16)。同样,与相应的T1,Al和B试剂相比,烯丙基锌试剂以更高的产率得到加合物。
