function with an acidic NH group were prepared using the direct insertion of zinc dust into the corresponding alkyl iodides in THF or THF:DMSO mixtures. Most of the starting iodides were obtained from natural α-amino acids and the resulting zinc species afforded after transmentalation with CuCN·2LiCI and reaction with a selection of relatively reactive electrophiles a variety of polyfunctional 1,2-amino
通过将锌粉直接插入相应的THF或THF:DMSO混合物的烷基碘中,制备了几种在β位带有氨基甲酸酯基或具有酸性NH基团的酰胺基官能团的锌有机金属锌。大部分起始碘化物均来自天然α-氨基酸,并在经过CuCN·2LiCl离子化反应后,与一些相对反应性的亲电子试剂反应,以光学纯的形式生成了多种多官能的1,2-氨基醇衍生物和氨基甲酸酯,从而提供了所得的锌物种。形式。将几种仲β-酰胺基烷基碘化物转化为相应的手性锌试剂,并用亲电子试剂捕获。研究了手性仲有机锌化合物的构型稳定性及其反应的立体化学过程。
