Conversion of alcohols to bromides using a fluorous phosphine
Desmaris, Laurence,Percina, Nathalie,Cottier, Louis,Sinou, Denis
, p. 7589 - 7591 (2003)
Reaction of alcohols with the fluorous phosphine-carbon tetrabromide complex in toluene or in a two-phase toluene-FC-72 system afforded the corresponding bromides in good yields. The fluorous-phosphine oxide is readily separated by liquid-liquid extraction, providing an alternative to the homogeneous triphenylphosphine-carbon tetrachloride conversion, as well as to the polymer-supported phosphine method. The fluorous phosphine oxide could be reduced and the product reused.
Synthesis of Deoxyhalogenosugars. Reaction of Halide Ions with 1,2,3,4-Tetra-O-acetyl-6-O--β-D-glucopyranose
Ambrose, Michael G.,Binkley, Roger W.
, p. 674 - 677 (1983)
The reaction of bromide, chloride, and iodide ions with 1,2,3,4-tetra-O-acetyl-6-O--β-D-glucopyranose under the proper conditions gives excellent yields of the corresponding deoxyhalogeno sugars.Deoxyiodo sugars form readily under all conditions studied.Difficulties with displacements by bromide and chloride are encountered but can be overcome by appropriate modification of reaction conditions.Displacement with fluoride ion is difficult and produces only a low yield of the expected fluorinated carbohydrate.

The regioselective and efficient bromination of primary hydroxyl groups in unprotected carbohydrates or glycosides is successfully achieved by using (chloro-phenylthio-methylene)dimethylammoniumchloride (CPMA) in the presence of tetrabutylammonium bromide
Synthesis and Properties of Glucose and Galactose Phosphonate Derivatives
Padyukova, N. Sh.,Afsar, S.,Dixon, H. B. F.,Karpeiskii, M. Ya.
, p. 328 - 331 (2007/10/02)
Phosphonate analogs of glucose-6-phosphate and galactose-6-phosphate, namely, 6-deoxy-6-phosphono-α,β-D-glucopyranose and 6-deoxy-6-phosphono-α,β-D-galactopyranose, were synthesized.They were shown to be weak inhibitors of 1L-myo-inositol-1-phosphatase. Key words: 6-deoxy-6-phosphono-α,β-D-glucopyranose, 6-deoxy-6-phosphono-α,β-D-galactopyranose, 1L-myoinositol-1-phosphatase, inhibitors
