Nucleophilic trifluoromethylation of conjugate acceptors via phenyl trifluoromethyl sulfone
摘要:
A mild procedure for the conjugate addition of the trifluoromethyl anion to activated Michael acceptors such as arylidenemalononitriles (15 examples) and arylidene Meldrum's acids (9 examples) using phenyl trifluoromethyl sulfone through a reductive magnesium metal mediated procedure is described. The new methodology is used to prepare befloxatone, a reversible and selective monoamine oxidase A inhibitor. (C) 2013 Elsevier Ltd. All rights reserved.

intermolecular Stetter reaction of aromaticaldehydes with 2-bromo-3,3,3-trifluoropropene is achieved by the in situ generated α-trifluoromethyl carbanion catalyst. It not only represents the first example for α-trifluoromethyl carbanion-catalyzed umpolung reaction but also reveals a new protocol for the umpolung of aldehydes. Various useful β-alkoxyl-β-trifluoromethylated ketones were obtained in high yields
