Abstract

A modified procedure for synthesis of sucrose was carried out by using purified crystalline 1, 3, 4, 6-tetra-O-benzoyl-D-fructofuranose in place of 1, 3, 4, 6-tetra-O-acetyl-D-fructofuranose; namely, reaction of 1, 2-anhydro-3, 4, 6-tri-O-acetyl-α-D-glucopyranose with tetrabenzoyl-D-fructose at 110_??_118°C for 3 hr followed by deacylation, and by chro-matographic separation of the deacylated product afforded crude sucrose. Acetylation of the synthetic product gave octaacetate sucrose in the yield of 5.0%.
