Abstract
Methods for preparing ester derivatives of 3-methyl-2-buten-1-ol (prenyl alcohol) from 2-methyl-1,3-butadiene (isoprene) and alkanoic acids in the presence of an inorganic acid catalyst are disclosed. The resultant prenyl ester (e.g., prenyl acetate) can be converted to prenyl alcohol by reaction with water in the presence of either a suitable enzyme or a base. Prenyl alcohol can be readily converted to citral, a chemical intermediate in the synthesis of vitamins A and E, and several widely-used carotenoids
