conjugate-nucleophilic addition of acetylenic sulfones, phenylselenomagnesium bromide, and carbonyl compounds, such as aldehydes, aliphatic ketones, or alpha,beta-unsaturated enals or enones. The reaction is highly regio- and stereoselective with moderate to good yields. Functionalized allylic alcohols were obtained in the case of aldehydes and aliphatic ketones. In the case of alpha,beta-unsaturated enones, functionalized
通过炔属砜,苯基硒化镁溴化物和羰基化合物(例如醛,脂肪族酮或α,β-不饱和烯醛或烯酮)的三组分共轭亲核加成反应,合成了β-苯基硒基-α-甲苯磺酰基取代的烯烃。该反应是高度区域和立体选择性的,产率中等至良好。在醛和脂族酮的情况下获得官能化的烯丙醇。在α,β-不饱和烯酮的情况下,根据酮的结构,获得官能化的烯丙基醇或官能化的γ,δ-不饱和酮。
