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.

A series of alpha-(1 --> 5)-linked L-arabinofuranosyl di-, tetra-, hexa- and octameric derivatives were synthesized efficiently. The process was carried out in a regio- and stereoselective manner using perbenzoylated arabinofuranosyl trichloroacetimidates as glycosyl donors and unprotected or partially protected arabinofuranosides as glycosyl acceptors in the presence of a catalytic amount of trimethylsilyl
