Reaction Steps
A mixture of 4.24 g. of 3,5-diacetyl-4,6-dihydroxy-2H-pyran-2-one, 2.12 g. of benzaldehyde, 20 drops of piperidine and 75 ml. of chloroform is refluxed for eight hours. The water liberated during the reaction is removed by a receiver. The reaction mixture is concentrated and triturated with ethanol to afford 5-acetyl-3-cinnamoyl-4-hydroxy-2H-pyran-2,6(3H)-dione, m.p. 154°-155° C.
