Abstract 1,6-Disulfide-bridged derivatives have been prepared for d-gluco-, d-manno-, d-allo-, d-galacto-, and d-talo-pyranose, in the main by the nucleophilic attack of a C6 thiolate onto an anomeric thiosulfonate. The d-gluco disulfide, ‘angyalosan’, was successfully oxidized to a single thiosulfinate. * In celebration of the 90th birthday of Stephen J. Angyal. * The spectrum was obtained at 233 K and two sets of resonances were observed, assigned to two conformers, a and b. The 1H and 13C resonances for each conformer were assigned using COSY, HSQC, and HMBC two-dimensional spectra. † The 1H and 13C NMR spectra [300 MHz, (CD3)2SO] were uninterpretable at 293 K. § [1S,4S,5S,6S,7R]-5,6,7-Triacetoxy-8-oxa-2-thiabicyclo[3.2.1]octane. ¶ [1S,4S,5S,6S,7R]-5,6,7-Triacetoxy-8-oxa-2-selenabicyclo[3.2.1]octane. | ||||||||||||||||||||||||||||||||||||||||||
