Electrochemical méthoxylation of isopulegole (1̠) and α-pinene (2̲)

Abstract

In the course of our investigation on electrochemical synthesis the electrochemical méthoxylation of isopulegole (̲1) and α-pinene (̲2) was carried out. In the case of ̲1 product obtained was a very complex mixture with 3,4-dimethoxy- p-8(9)-menthene (3) as the major component. The méthoxylation of ̲2 yields sobrerol dimethyl diether [6,8-dimethoxy-p-l(2)-methane] (̲4) as the major component. The electrochemical methoxylatiorn of 3-carene, α-pinene or limonene gives in the described conditions a mixture of several compounds difficult to separate into indyvidual components.
