[reaction: see text] Nonenolizable aldehydes and ketones react with 2-chloroethanol and 3-chloropropanol under basic conditions (t-BuOK, DMF/THF) with formation of 2-substituted 1,3-dioxolanes and 1,3-dioxanes, respectively. Conversion of the two-step addition-alkylation process depends on the electrophilicity of the carbonyl group that governs the equilibrium of addition of chloroalkoxides. This method
the structure of the isocyanide. The use of an electron-deficient aryl isocyanide, such as 2c and 2d, is required to selectively obtain the monoinsertion product. When aryl isocyanides containing alkyl substituents, such as 2a and 2b, are employed, two molecules of the isocyanide are incorporated, and the double-insertion product is obtained. The reaction of tert-octyl isocyanide also induces a double
描述了布朗斯台德酸催化异氰化物正式插入缩醛的 CO 键。各种非环状和环状缩醛可以应用于催化插入以形成 α-烷氧基亚胺酸酯。官能团,例如硝基、氰基、卤素、酯和烷氧基,可以耐受所采用的反应条件。反应过程高度依赖于异氰化物的结构。需要使用缺电子的芳基异氰化物,例如 2c 和 2d,以选择性地获得单插入产物。当使用含有烷基取代基的芳基异氰化物,例如2a和2b时,引入两个分子的异氰化物,得到双插入产物。叔辛基异氰化物的反应也诱导了双重掺入,但随后的酸介导的断裂会导致 2-烷氧基亚胺酰氰化物。单插入产物 α-烷氧基亚胺酸酯可以很容易地水解为 α-烷氧基酯,从而实现缩醛的正式羰基化。
