Lithium/zinc transmetallation with the cyclic organolithium intermediate 3 (prepared by intramolecular carbolithiation of the initially formed organolithium 2) gives the corresponding organozinc intermediate 5. Copper- or palladium-promoted SN2′ reactions between compound 5 and allylic or propargylic halides, as well as arylation, vinylation, benzylation, acylation, and conjugate addition to α,β-unsaturated
