  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.
