  Hydrogen peroxide oxidation of polysubstituted pyrylium salts: formation of enol esters and furans

  摘要：

  2,4,6-Trialkylsubstituted pyrylium salts 1 have been known lo afford 2-acyl-3,5-dialkyl-furans 2 in moderate yields (30 - 45%). Oxidation of these salts in buffer solutions (pH = 3 - 4.5) increased the yields of acylfurans to 75%. In contrast, tetra- and penta-substituted pyrylium salts are mainly converted into enol esters with a delta-keto group and furans all originating presumably by C-O bond cleavages in a common intermediate. This intermediate may result by a C-O acyl shift as inferred from analogous compounds with deuterium labelling.
