Addition of carbon nucleophiles to cyclic N-tosyliminium ions, derived from α-hydroxy and α-methoxy tosylamides (5a,b and 6a,b, respectively) is described. In general, good to excellent yields were obtained when allytrimethylsilane, 1-tbutyldimethylsilyloxy-1-ethoxyethane, and trimethylsilyl cyanide were used as nucleophiles.
描述了将碳亲核试剂加到衍生自α-羟基和α-甲氧基甲苯磺酰胺(分别为5a,b和6a,b)的环状N-甲苯磺酰亚胺鎓离子上。通常,当使用烯丙基三甲基硅烷,1-叔丁基二甲基甲硅烷基氧基-1-乙氧基乙烷和三甲基甲硅烷基氰化物作为亲核试剂时,可获得良好至优异的产率。
