ABSTRACT:
In accordance with the present invention, a method for the interconvertion of the enantiomers of acyclic 1,2-dihydroxy-3-alkenes or for converting either enantiomer of acylic 1,2-dihydroxy-3-alkenes to the corresponding antipodal 1-hydroxy-2-alkoxy-3-alkene compounds has been discovered, comprising reacting in an acidic reaction media either enantiomer of an acylic vinyl epoxide (which can be derived from the corresponding acyclic 1,2-dihydroxy-3-alkene) with water, alcohol, or a mixture thereof. When substantially optically pure acyclic vinyl epoxide compounds are employed in the inventive method, the interconverted acyclic 1,2-dihydroxy-3-alkene or 1-hydroxy-2-alkoxy-3-alkene compound products are also substantially optically pure.
