Compounds 2-7 were prepared by the acid-catalysed ketalization of glycerol. Org. Synth. Coll. VoI III 1955, 502. Aldehydes corresponding to compounds 8-13 produce the mixture of the dioxan-5-ol and dioxolane-4-methanol under the same conditions.

    • 20. The acetal and ketal exchange reactions were performed between (R)-solketal butyrate (66 % ee) and the carbonyl compound in the presence of acid Amberlyst 15 ion-exchange resin. Acyl migration was insignificant as indicated by only slight racemication.

    • 28. Initial composition and the enzymatic reaction was analyzed by the GLC method after derivatization with acetic and propionic anhydride, respectively (ref. 19). Total conversion was calculated by equation: (equation presented), the term re designating ring isomeric excess with respect to the ring isomer cited in the superscript, the subscripts as in ref. 22. It is assumed that the isomers have identical responses in FID-detection.
