A Facile Construction of Bi- or Tricyclic Skeletons by Nickel-Catalyzed Stereoselective Cyclization of Alkynylcycloalkanone
摘要:
A nickel-catalyzed intramolecular cyclization of alkynylalkanone in the presence of Et(3)SiH using an NHC ligand produced various carbo- and heterocycles In a stereoselective manner. The reaction would proceed via formation of oxanickelacycle followed by sigma-bond metathesis with silane to give a bi- or tricyclic compound.
