work, we developed an efficient method for the synthesis of β-d-fructofuranosides by using a 6-picoloyl-protected fructofuranosyl thioglycoside as the glycosyl donor. Subsequently, we applied the approach to a wide variety of donors and acceptors. Furthermore, the successful synthesis of levantetrose confirmed its applicability in the multistep synthesis of oligosaccharides.
beta-D-fructofuranoside 6-OH and 1-OH acceptors (3 and 6) gave stereospecifically the protected methyl levanobioside 12 and inulinobioside 17 in excellent yields (80 and 86%), respectively. Protecting group manipulations on these afforded new disaccharide 6'-OH and 1'-OH acceptors (13 and 19), which were coupled again with donor 11 (1.0 mol equiv) to yield methyl levanotrioside 14 and inulinotrioside 20 in
