REDUCTIVE CLEAVAGE OF AXIALLY DISYMMETRIC TERTIARY AMINES AND QUATERNARY AMMONIUM SALTS BY LITHIUM ALUMINIUM HYDRIDE. SYNTHESIS OF NEW 1,1'-BINAPHTHYL SUBSTITUTED AMINES

Axially disymmetric tertiary amines or quaternary ammonium salts A are synthesized by double alkylation of primary or secundary amines with racemic or optically pure 2,2'-bis(bromomethyl)-1,1'-binaphthyl.Their reductive cleavage by lithium aluminium hydri

METHODE SIMPLE DE SYNTHESE D'AGENTS DE TRANSFERT CHIRAUX PAR ACTION D'UN AGENT ALKYLANT A SQUELETTE BINAPHTYLE-1,1'

A general way for introducing axial chirality in phase transfer catalysts, by quaternarization with 2,2'-bis(bromomethyl)-1,1'-binaphtyl, is described and applied to l(-) ephedrine.One of the resulting catalysts gives 37 percent ee in epoxydation of chalcone.
