Description

General description

3,5-Dimethoxytoluene (DMT) is a methoxylated phenolic derivative. It is reported to be one of the main constituent of the floral volatiles in different rose varieties.[1] It has been biosynthesized from orcinol by two successive methylation catalyzed by O-methyltransferases (OMTs).[2] The features of its aerobic oxidation with metal/bromide catalysts have been investigated.[3]

Application

3,5-Dimethoxytoluene (DMT) may be used in the synthesis of 3,5-dimethoxybenzoic acid by oxidation[4] and 2-methoxy-6-methyl-1,4-benzoquinone by catalytic oxidation with hydrogen peroxide (H₂O₂)/methyltrioxorhenium (CH₃ReO₃) in dimethyl carbonate (DMC).[5]
