Abstract

Process for the synthesis of 2,6-dihydroxycycloinol, characterized in that it comprises, in a first step, the subjecting of very pure pinol to bromination in 2,6-dibromocinol with satic acetate and acetic acid; and in a second stage subjecting to hydrolysis, the latter with diluted solution of a mineral acid, such as sulfuric, at about 100ºC according to the following reactions: ** (see formula) ** Obtaining a mass that, in a third stage, is cooled, extracted and washed with chloroform; and in a final stage, the chloroform solution isolates the dihydroxycycloinol by evaporation and crystallization; and additionally because it is acted on an industrial scale.
