The Electrophilic Amination of Carbanions: An Unconventional New Entry to C−N Bond Formation

Autor: Pasquale Dembech, Giancarlo Seconi, Alfredo Ricci

Publikováno v: Chemistry - A European Journal. 6:1281-1286

The electrophilic amination of carbanions allows the preparation of a wide range of amines through an unconventional C−N bond-forming reaction. The concepts behind the varied synthetic approaches, classified by the nature of the aminating agent and

Silylcupration of N-phenyl-N-ethynyl-aniline: A versatile route to functionalized N,N-bis(phenyl)enamines

Autor: Gianna Reginato, Laura Capella, Dario Lazzari, Antonella Capperucci, Pasquale Dembech, Giovanni Curotto, Alfredo Ricci

Publikováno v: Tetrahedron Letters. 34:3311-3314

The silylcupration of N-phenyl-N-ethynyl-aniline, occurs regioselectively leading to silylation at the β-carbon atom. Subsequent reaction of the resulting vinyl copper adduct with electrophiles, opens a new flexible route to functionalized enamines.
