Abstract
Methyl ethers of compounds of the yohimbane series are produced by reacting the corresponding compounds with free alcoholic hydroxyl groups, other than yohimbine and a -yohimbine, with diazomethane in the presence of an aluminium alcoholate. In the examples, the compounds methylated are (1) methyl reserpate, (2) rescidic acid methyl ester and (3) methyl deserpidate. Another yohimbane compound specifically mentioned is seredin. Specification 928,129 is referred to.
