Deprotonation of α-amido sulfones 7 with BunLi at -90°C followed by reaction with electrophiles leads, depending on the substitution on the amidic nitrogen to enamides 10 (secondary amides 7a,b) or functionalised α-amido sulfones 12 (tertiary amides 7c,d).
在-90°C下用BunLi去质子化α-
氨基磺酸酯7,然后与电亲体反应,取决于
氨基氮的取代基,可以得到烯酰胺10(次级酰胺7a,b)或功能化的α-
氨基磺酸酯12(三级酰胺7c,d)。
