Vinyl sulphones (1) were subjected to nucleophilic addition by α-lithionitriles (2) and gave cyclized products, 3-oxothian 1,1-dioxides (3) or cyclopropane derivatives (4), in satisfactory yields according to the substituents on the reagents. The cyclopropanation reactions could be extended to the formation of cyclopropyl sulphides (12)–(16) in good yields.
根据试剂上的取代基,以令人满意的收率,将乙烯基砜(1)通过α-锂离子(2)进行亲核加成,得到环化产物3-氧杂环丁烷1,1-二氧化物(3)或环丙烷衍生物(4)。 。环丙烷化反应可以以高收率扩展到环丙基硫化物(12)-(16)的形成。
