A highly stereoselective vinylogous Pummerer rearrangement involving 1,4-migration of the sulfinyl oxygen atom occurs when ortho-sulfinyl benzyl carbanions are treated with trimethylsilyl halides. The reaction proceeds in good yield and affords optically pure benzyl alcohols with extremely high enantioselectivity (ee > 98%).
当邻亚磺酰基苄基碳负离子用三甲基硅基卤化物处理时,会发生涉及亚磺酰基氧原子1,4-迁移的高度立体选择性的插烯Pummerer重排反应。该反应产率良好,可提供对映体纯度极高(对映体过量>98%)的苄醇。
