A novel DMSO-involved cascade reaction of stabilized sulfonium salts has been established for direct construction of polyfunctional furans. This one-pot sequential reaction involving in situ generated α-methylene sulfonium salts was followed by [4 + 1] annulation with sulfur ylides. Notably, DMSO plays a very important role in this transformation, not only as a solvent but also as one carbon source.
已建立了一种新型的涉及二甲基亚砜(DMSO)的稳定锍盐级联反应,用于直接构建多官能团呋喃。这种一锅法连续反应涉及原位生成的α-亚甲基锍盐,随后与硫叶立德进行[4 + 1]环化反应。值得注意的是,DMSO在这种转化中起着非常重要的作用,不仅作为溶剂,还作为一个碳源。
