L-Cladinose (1) and its C-3 epimer 2 were synthesized through a highly stereoselective addition of methyl anion to the C-3 carbonyl groups of alpha-anomer 9 and beta-anomer 10 having 2,6-anhydro-2-thio structures, respectively, which were prepared from the common intermediate 6 in stereocontrolled fashion.
