Regio- and stereoselective synthesis of furanosyl oligosaccharides in moderate to very good yields using arabinofuranosyl trichloroacetimidates as glycosyl donors and unprotected or partially protected glycosides as acceptors was described. A convergent synthesis of 1 → 5-linked α-l-arabinofuranosyl octamer was presented.
