  One-Pot Synthesis of 3-Hydroxyquinolin-2(1H)-ones from N-Phenylacetoacetamide via PhI(OCOCF₃)₂-Mediated α-Hydroxylation and H₂SO₄-Promoted Intramolecular Cyclization

  摘要：

  A clean, one-pot synthesis of the biologically important 3-hydroxyquinolin-2(1H)-one compounds has been realized from the readily available N-phenylacetoacetamide derivatives through a PhI(OCOCF3)(2)-mediated alpha-hydroxylation and a H2SO4-promoted intramolecular condensation. The hydroxyl group in the generated alpha-hydroxylated intermediate can be well tolerated in the second H2SO4-promoted cyclization step.

  The reaction of phenyliodine bis(trifluoroacetate) (PIFA) with a series of anilides 1 (E = CO2Et) In CF3CH2OH was found to give 3-hydroxy-2-oxindole derivatives 2, while that with various anilides 1' (E = CON(R-4)Ar) afforded the C-2-symmetric or unsymmetric spirooxindoles 3. These processes feature a metal-free oxidative C(sp(2))-C(sp(3)) bond formation, followed by oxidative hydroxylation or spirocyclization.
