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
DMSO涉及的稳定sulf盐的级联反应,用于直接构建多官能
呋喃。涉及原位生成的α-亚甲基sulf盐的一锅顺序反应,然后用
硫酰化物进行[4 +1]环化。值得注意的是,
DMSO在这一转变中扮演着非常重要的角色,不仅作为溶剂,而且作为一种碳源。
