We investigated the stereoselective coupling of thymine with sulfoxides derived from meso-thiolane-3,4-diol via the Pummerer reaction. The introduction of 2,4-dimethoxybenzoyl groups to the hydroxyl groups of meso-thiolane-3,4-diol-1-oxide was effective to afford (2R∗, 3R∗, 4S∗)-1-[3,4-di-O-(2,4-dimethoxybenzoyl)thiolane-3,4-diol-2-yl]thymine stereoselectively.
