sulfones, which were readily available by the addition of pyrrolidine to vinylic or allylic sulfones, were converted to the corresponding α-alkylated vinylic sulfones through α-alkylation followed by elimination of pyrrolidino group. Some of the α-alkylated vinylic sulfones were further transformed to the corresponding allylic sulfones.
2-吡咯烷烷基对甲苯基砜很容易通过将吡咯烷加成到乙烯基或烯丙基砜中而获得,通过 α-烷基化随后消除吡咯烷基,转化为相应的 α-烷基化乙烯基砜。一些α-烷基化乙烯基砜进一步转化为相应的烯丙基砜。
