Alkylation of delocalized anions resulting from metallation of N-phenyl thioimidoesters (precursors of dithioesters and thiolesters) takes place on nitrogen with “saturated” thioimidoesters (alkane thiomidates). On the contrary, unsaturated thiomidoesters (α or β-ethylenic, α-arylated) are regioselectively alkylated on the α carbon atom by alkyl or allylic halides. The possibilities for synthesis offered
由N-苯基硫代亚酰胺基酯(二硫代酯和硫代酸酯的前体)的金属化导致的离域阴离子的烷基化在氮上与“饱和”硫代亚氨基酯(烷硫代氨基甲酸酯)发生。相反,不饱和硫代亚氨基酯(α或β-烯键式,α-芳基化)被烷基或烯丙基卤化物在α碳原子上区域选择性烷基化。萜烯化合物lavandulal(和lavandulol)和ar-姜黄烯的合成说明了通过连续使用硫亚氨基酯和二硫酯官能团的反应性(特别是允许在两个邻位碳上进行两次亲电加成)而提供的合成可能性。
