Copper-Catalyzed Domino SN2′/Coupling Reaction: A Versatile and Facile Synthesis of Cyclic Compounds from Baylis–Hillman Acetates

A variety of substituted quinoline/pyridine, thiochromene and naphthalene derivatives, which might be of biological and medicinal value, were syn- thesized by copper-catalyzed domino SN2'/coupling, SN2'/deacylation/coupling and SN2'/coupling/elimina- tion reactions. The method provides a general and convenient approach to the synthesis of various sub- stituted cyclic compounds from the corresponding Baylis-Hillman (B-H) acetates and N-/S-/C-nucleo- philes.
