Chiral pyrrolidines and piperidines from enantioselective rhodium-catalyzed cascade arylative cyclization

A new rhodium-catalyzed asymmetric arylative cyclization of nitrogen-tethered alkyne-enoate with arylboronic acids is described. In this process two new carbon-carbon bonds and one stereocenter are formed, providing access to pyrrolidines and piperidines

Nickel-mediated cyclization of enynes under an atmosphere of carbon dioxide

Nickel-mediated carboxylation of α,ω-enyne was investigated. In the presence of a stoichiometric amount of zero-valent nickel complex, enynes having an electron-withdrawing group on alkene reacted with carbon dioxide via intramolecular cyclization to affo
