effective method for the synthesis of 2-C-branched disaccharides, glycoconjugates, and nucleoside analogues is described. 1,2-(acetylcyclopropane)-annulated D-lyxofuranose underwent ring opening catalysed by CH3SO3H to act as an efficient glycosyl donor and give the glycosylation products in good yields and with high dia-stereoselectivities.
