Summary:Process for the preparation of S-2,2-R1,R2-1,3-dioxolane-4-methanol wherein R1 and R2 are each independently H or an alkyl group or wherein R1 and R2 together with the carbon atom to which they are attached form a carbocyclic ring by subjecting a mixture of R- and S-2,2-R1,R2-1,3-dioxolane-4-methanol to the action of a microorganism or substance derived therefrom which is capable of stereoselective consumption of R-2,2-R1,R2-1,3-dioxolane-4-methanol preferably until at least 50 wt% of the R-2,2-R1,R2-1,3-dioxolane-4-methanol is consumed. Various microorganisms are disclosed as suitable for the purpose.
