Rapid oligosaccharide synthesis using a fluorous protective group

The Bfp-OH, a novel fluorous protecting reagent, was able to be easily prepared. The Bfp group was readily introduced to a carbohydrate, removed in high yield, and recyclable after cleavage. The use of the Bfp group made it possible to synthesize a pentasaccharide by minimal column chromatography purification. Each synthetic intermediate was able to be easily purified only by simple fluorous-organic solvent extraction and monitored by TLC, NMR, and MS.

Selective Silylation of β-D-Galactosides. A New Approach to the Synthesis of (1->6)-β-D-Galactopyranooligosaccharides.

A simple and convenient synthesis of β-D-galactopyranose derivatives selectively modified at C-1 and C-6 is described.A key feature is the selective protection of the 6-OH group of methyl-, allyl-,and (p-nitrophenyl)-β-D-galactopyranosides using tert-buty
