Single-Electron-Transfer-Induced C(sp3)–N Couplings via C–C Bond Cleavage of Cycloketoxime Esters
摘要:
A practical single-electron-transfer-induced selective C(sp(3))-N coupling of cycloketoximes with anilines via C-C bond cleavage under copper-catalytic and synergetic photoredox/copper-catalytic reaction systems has been uncovered. These two powerful and simple protocols demonstrated excellent selectivity and good functional group compatibility without any base or ligand control. Preliminary mechanistic experiments indicated that a radical-mediated process was involved in these transformations.

A novel copper-catalyzed C(sp3)–N coupling of cycloketone oxime esters with nitrogen nucleophiles has been realized. All of the N-aryl/alkylanilines, anilines and benzophenoneimine could be employed in this protocol to produce a variety of 1°, 2° and 3° alkyl amines in one or two steps. These resultant cyano-containing alkyl amines were proven to be versatile synthetic building blocks in a variety

A method for preparing a functionalized polymer, the method comprising the steps of: (i) polymerizing monomer with an anionic initiator to form a reactive polymer; and (ii) reacting the reactive polymer with a nitrile compound containing a protected amino group, where the protected amino group is directly attached to a moiety selected from the group consisting of acyclic moieties, heterocyclic moieties, and non-aromatic cyclic moieties.
