Regioselective 4-demethoxylation of 1-n-alkyl-3,4,5-trimethoxybenzenes: a key step in the synthesis of olivetol and its homologues
Abstract
Selective removal of the 4-methoxy group in 1-n-alkyl-3,4,5-trimethoxybenzenes was performed under electron-transfer conditions; a new synthesis of olivetol dimethyl ether is described.
