摘要

Triacetic lactone, 4-hydroxycoumarins, and kojic acid derivative were subjected to anodic oxidation in MeOH containing LiClO 4 or NaCN to afford the corresponding methoxy or cyano compounds. In a basic media, however, dipyrone and dicoumarol were produced from triacetic lactone and 4-hydroxycoumarin, respectively. The formation process of 3- methoxytriacetic lactone as well as of 3-cyanotriacetic lactone is also presented.
