Abstract
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 arabinofur anosyl trichloroacetimidates as glycosyl donors and unprotected or partiall y protected arabinofuranosides as glycosyl accepters in the presence of a c atalytic amount of trimethylsilyl trifluoromethanesulfonate (TMSOTf).
