Syntheses and UV Spectroscopic Study of Mono- and Dialkyloxy-4-methylcoumarins
Mono- and dialkyloxy-4-methylcoumarins were successfully synthesized starting from dihydroxy-4-methylcoumarins and an alkyl bromide, butyl bromide or octyl bromide, at 1:1 molar ratio. The alkylation of 5,7-dihydroxy-4-methylcoumarin gave 5,7-dialkyloxy-4-methylcoumarin and two monoalkyloxy-4-methyl...
