The copper(II) trifluoromethanesulfonate-catalyzed Pummerer reaction of β-ketosulfoxides with 1,3-dicarbonyl compounds or π-nucleophiles such as phenols, arenes, and tetraallylsilane is reported. The mild conditions provide an efficient entry to a novel class of polysubstituted 3-alkylthiofuran and polysubstituted 3-thiobenzofuran heterocycles from readily available materials.
据报道,β-酮亚砜与1,3-二羰基化合物或π-亲核试剂(例如苯酚,芳烃和四烯丙基硅烷)的三氟甲磺酸铜(II)催化Pummerer反应。温和的条件从容易获得的材料中有效地进入了新型的多取代的3-烷基硫呋喃和多取代的3-硫代苯并呋喃杂环。
