Page/Page column 185-186, (2018/02/28)
Compositions and methods for the treatment of bacterial infections include compounds containing dimers of cyclic heptapeptides conjugated to one or more monosaccharide or oligosaccharide moieties. In particular, compounds can be used in the treatment of bacterial infections caused by Gram-negative bacteria.

1,3-Dimethylimidazol-2-ylidene borane and 2,4-dimethyl-1,2,4-triazol-3- ylidene borane are found to be useful reagents for the reduction of alkyl iodides and bromides bearing nearby electron withdrawing substituents. Signatures of radical chain reactions are seen in many cases, but ionic reductions may also be occurring with some substrates. The reagents are attractive because of their low molecular weight, their availability from inexpensive precursors, and their stability. Separation of the borane products from the target products is readily accomplished either with or without prior regeneration of the borane for later reuse. 2,4-Dimethyl-1,2,4-triazol-3-ylidene borane is versatile because both starting borane and its derived products can be removed by extraction with water.

Synthesis of Deoxyhalogenosugars. Reaction of Halide Ions with 1,2,3,4-Tetra-O-acetyl-6-O--β-D-glucopyranose

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.
