- W2364007768 abstract "4-methyl-7-hydroxycoumarin,acetic anhydride were used as main materials to synthesis 4-methyl-7-acetoxycoumarin by two methods,One was direct esterification of 4-methyl-7-hydroxycoumarin with acetic anhydride,the other was reacting of acetic anhydride with 4-methyl-7-hydroxy coumarin′ sodium salt, the construction of title compound was confirmed by m.p.、 elemental analysis、 IR and UV.comparing two methods based on the experiments,the results show that the latter method has advantages of good yield and simple operation." @default.
