Synthesis of 4-halo-2 (5H)-furanones and their suzuki-coupling reactions with organoboronic acids. A general route to 4-aryl-2 (5 H) -furanones
Abstract
4-Halo-2(5H)-furanones were prepared by the halolactonization of 2,3-allenoic acids. The subsequent Suzuki coupling reaction of 4-halo 2(5H)-furanones with aryl boronic acids was carried out to produce 4-aryl-2(5H)-furanones in excellent yields.
