Syntheses of hitherto unreported heterocycles, such as oxathiocine derivatives, in excellent yields, and a doubly cyclized oxathiocine derivative, through a Wittig olefination and intramolecular Heck reaction sequence via an unusual 8-endo-trig cyclization, are reported.
据报道,通过 Wittig 烯化和分子内 Heck 反应序列,通过不寻常的 8-endo-trig 环化,以优异的产率合成了迄今为止未报道的杂环化合物,例如氧硫辛衍生物,以及双环化的氧杂硫辛衍生物。
