2-Fluoropyridinyl-6-oxy- precursors derived from phenyl vinyl sulfide react with radicals generated from xanthates via an addition–elimination process to furnish the corresponding vinyl sulfides in good yields. This convergent method is operationally simple and enables a straightforward synthesis of the difficult to access tetrasubstituted vinyl sulfides. Vinyl sulfides were used as more robust enol ether surrogates
衍生自苯基乙烯基硫化物的2-氟吡啶基-6-氧基-前体与黄原酸酯生成的自由基通过加成-消除过程反应,从而以高收率提供了相应的乙烯基硫化物。这种会聚方法操作简单,可直接合成难以获得的四取代乙烯基硫化物。乙烯基硫化物在与N-酰基阳离子发生高度立体选择性的反应中,被用作更坚固的烯醇醚替代物,从而导致含氮多环结构。
