Polysubstituted furans are versatile building blocks in organic synthesis and are widely spread over in variety of natural products, pharmaceuticals and functional materials. Herein, we report a convenient, facile and economic approach for the synthesis of polysubstituted furans through a tandem O−H insertion/[3,3]-sigmatropic rearrangement of rhodium carbenoids with easily available furfuryl alcohols. This protocol
多取代呋喃是有机合成中的通用构件,广泛应用于各种天然产物、药物和功能材料中。在此,我们报告了一种方便、简便且经济的合成多取代呋喃的方法,通过串联的 O-H 插入/[3,3]-sigmatropic 重排铑卡宾与容易获得的糠醇。该协议的特点是操作简单、效率高、产量高、底物范围广、官能团耐受性更强。
