Parent aliphatic and aromatic β enamino sulphoxides bearing secondary and tertiary alkylamino residues are synthesized by mixing of alkylamine hydrochlorides with metallated enolates of the β-oxosulphoxides in methanol. The latter compounds are obtained in very good yields from metallated sulphoxides and tertiary amides at room temperature in tetrahydrofuran. The majority of the products have enaminic
带有仲和叔烷基氨基残基的母体脂族和芳族β-烯氨基亚砜是通过将烷基胺盐酸盐与β-氧亚砜的金属化烯醇化物在甲醇中混合而合成的。后者的化合物是在室温下在四氢呋喃中从金属化的亚砜和叔酰胺以很高的产率获得的。大多数产物在氯仿溶液中具有烯胺结构,并且具有分别具有叔和仲β-烷基氨基残基的E和Z构型。
