A novel substituted diene alcohol represented by a general formula:
wherein X represents a group of the formula
and a process for the preparation thereof wherein a lower alkoxycarbonyl group of a substituted diene carboxylic acid ester having an E configuration obtained by the treatment of a chrysanthemic acid ester with Bronsted acid or a substituted diene carboxylic acid ester having a Z configuration obtained by the thermal cleavage of a chrysanthemic acid ester is reduced to methylol derivative.
