Abstract
PURPOSE: The reaction of a 1,3-dicarbonyl compound and a cyclic carbonic ester is conducted in the presence of a catalyst such as a tertiary amine or quaternary ammonium salt to produce the titled compound in high yield under mild reaction conditions.
CONSTITUTION: The reaction of a compound of formulaI(R1 is hydrocarbon residue; R2 is H, hydrocarbon residue; R3 is hydrocarbon residue, alkoxy; where, when R2 is hydrocarbon residue, R3 is hydrocarbon residue) such as 3-methyl-2, 4-pentanedione or ethyl acetoacetate with another compound of formula II R4 is H, alkyl), e.g., ethylene carbonate is conducted in the presence of a tertiary amine such as trialkylamine, quaternary ammonium halide or alkali metal halide at 150W180°C to give the objective compound of formula III. The amount of the catalyst is 0.01W1, preferably about 0.1mol per mol of the compound of formula II.
