Methylmanganese pentacarbonyl-mediated transformation of enynes to cyclopropanated bicyclic compounds and cyclopentanes bearing an exocyclic double bond has been carried out. Control of the product distribution can be achieved by changing reaction conditi

A series of monocyclic and bicyclic heterocycles with exocyclic alkenes were constructed in a stereoselective fashion by an organozinc/Ni(COD)2 - mediated cyclization of alkynyl enones. Both reductive and alkylative cyclization manifolds were accessible depending on the ligand and organozinc structure. Alkylative cyclizations were generally more efficient than reductive cyclizations, particularly with cyclic substrates.
