Zusammenfassung:Disclosed is (4R-cis)-1,1-dimethylethyl-6-iodomethyl- -2,2-dimethyl-1,3-dioxane-4-acetate of the general formula (II); process of the synthesis thereof; which process can be characterised in reacting a compound of the general formula (II) representing a phenyl group substituted by one or two substituents selected from halogen or nitro, with an alk. iodine in a solvent at 0 degrees Celsius up to a backflow of the used solvent; 6-aryl-sulfonyloxymethyl intermediates of the general formula (II) wherein Ar is as defined, for the production of the formula (III) compounds. Opisuje sa (4R-cis)-1,1-dimetyletyl-6-jódmetyl-2,2- -dimetyl-1,3-dioxán-4-acetát vzorca (III), spôsob jeho syntézy, pri ktorom sa na zlúčeninu všeobecného vzorca (II), kde predstavuje fenylskupinu substituovanú jedným alebo dvoma substituentmi zvolenými zo súboru zahŕňajúceho halogény a nitroskupinu, pôsobí alkalickým jodidom v rozpúšťadle pri teplote od 0 °C do teploty spätného toku použitého rozpúšťadla, a 6-arylsulfonyloxymetylové medziprodukty všeobecného vzorca (II), kde Ar má uvedený význam, na výrobu zlúčeniny vzorca (III).ŕ
