title: Synthesis and stereochemistry of 6-deoxy-6-halogeno-D-glucofuranose cyclic phosphates.
abstract: 1, 2-O-Cyclohexylidene- and 1, 2-O-isopropylidene-alpha-D-glucofuranose react with hexa-alkylphosphorous triamides to give the corresponding 3, 5, 6-phosphites. Treatment of the latter compounds with chlorine and bromine affords 1, 2-substituted 6-deoxy-6-halogeno-alpha-D-glucofuranose 3, 5-phosphorohalogenidates. Replacement of halogen at phsophorus by hydroxyl and amino groups has been investigated. Cyclic phosphorohalogenidates isomerize in N, N-dimethylformamide. The stereochemistry of the compounds investigated was established by using 1H- and 13C-n.m.r. data.
