Abstract
Polysubstituted furans are versatile building blocks in organic synthesis and are widely spread in a 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 is characterized by its operational simplicity, high efficiency with excellent yields, broad substrate scope, and great functional‐group tolerance.
