Synthesis of (1->5)-β-D-galactofuranan and cyclo5)-β-D-galactofurano>oligosaccharides

Article abstract of DOI:10.1007/BF00699946

Synthesis of a linear (1->5)-β-D-galactofuranan was accomplished by trityl-cyanoethylidene polycondensation.On 10-fold reduction in the monomer concentration, the condensation products are cyclic oligosaccharides; the formation of 1,5-anhydro-α-D-galactofuranose was also demonstrated. - Key words: 3,6-di-O-benzoyl-5-O-trityl-1,2-O-<(1-cyano)ethylidene>-α-D-galactofuranose, polycondensation; (1->5)-β-D-galactofuranan, cyclooligomerization, concentration dependence; cyclooligosaccharides; 1,5-anhydro-α-D-galactofuranose.
