| abstract | The present invention is directed to a process for isomerizing a pent-l-en-3-ol according to formula (1) to a mixture of the stereoisomers Z-pent-2-en-1-ol (2) and E-pent-2-en-1-ol (3) according to formulae (2) and (3) wherein R 1 is selected from alkyl, aryl, and alkylaryl radicals, R 2 is selected from H, alkyl, and aryl radicals; which process comprises reacting the pent-1-en-3-ol (1) in the presence of a heterogeneous acid catalyst either in water or in a multiphase solvent system. The heterogeneous acid catalyst is preferably selected from the group consisting of Brønsted acids on a carrier, strong acidic cation exchangers and polymers having acidic groups. The products of the process according to the present invention are important intermediates for the manufacture of isoprenoids such as vitamin A and derivatives thereof and carotenoids. |
