  Facile One-Pot Synthesis of N-Difluoromethyl-2-pyridone Derivatives

  摘要：

  A novel one-pot synthesis of N-difluoromethyl-2-pyridones is described. N-(Pyridin-2-yl) acetamide derivatives were excellent precursors for the preparation of N- difluoromethyl-2-pyridone derivatives. Difluoromethylation of 2-acetaminopyridine derivatives was achieved with sodium chlorodifluoroacetate as a difluorocarbene source in the presence of a catalytic amount of 18-crown-6. Subsequent in situ hydrolysis of resultant 1,2-dihydro-2-acetimino-1-difluoromethylpyridines proceeded under mild acidic conditions to afford the corresponding N-difluoromethyl-2-pyridones in moderate to good yields.

  The effective difluoromethylations of various S- and O- based- nucleophiles, presenting a wide range of pKa values, using diethyl(bromodifluoromethyl) phosphonate (1) under basic conditions is described. These reactions, which rely on the quantitative generation of difluorocarbene formed through the hydrolysis of 1, were found to be effective only once the starting materials had pKa values of less
