Synthesis of 3-Haloindolizines by Copper(II) Halide Mediated Direct Functionalization of Indolizines

3-Haloindolizines were synthesized via Cu(II) halide mediated halogenation of indolizines. This C−H direct functionalization process occurred under mild conditions giving 3-haloindolizines in moderate to excellent yields, and the products obtained were tested under the Suzuki−Miyaura reaction providing 3-arylindolizines in high yields.
