Tetrakis(dimethylamino)ethylene (TDAE) Mediated Addition of Heterocyclic Difluoromethyl Anions to Heteroaryl Aldehydes. A Facile Synthetic Method for New gem-Difluorinated Alcohols Derived from 4-Bromo-1-naphthylamine and 8-Quinolylamine

Abstract

New heterocyclic-CF2CHOH-Ar derivatives, derived from N,N-dimethyl-4-bromo-2-difluoracetyl-1-naphthylamine and N,N-dimethyl-5-difluoroacetyl-8-quinolylamine, are easily obtained in moderate to good yields from the tetrakis(dimethylamino)ethylene (TDAE) mediated reduction of the corresponding - COCF2Cl starting materials in the presence of heteroaryl aldehydes.
