  α-Dimethylaminomethylenation-induced Houben–Hoesch-type cyclization of cyanoacetanilides: a practical synthesis of 3-formyl-4-hydroxyquinolin-2(1H)-ones

  摘要：

  The tandem reaction of cyanoacetanilides with triflic anhydride in DMF proceeded at room temperature to afford 3-formyl-4-hydroxyquinolin-2(1H)-ones in good to high yields. A detailed mechanistic study revealed that the tandem reaction proceeded via alpha-dimethylaminomethylenation, which promoted the subsequent Houben-Hoesch-type cyclization. Both alpha-functionalization and the cyclization steps were optimized, and a multi-gram scale synthesis of 3-formyl-4-hydroxyquinolin-2(1H)-one was achieved. (C) 2011 Elsevier Ltd.
