title: 6-Thio and -seleno-beTa-D-glucose esters of dimethylarsinous acid.
abstract: Syntheses of 2-Se-(1,2,3,4-tetra-O-acetyl-beta-D-glucopyranosyl)-3-N,N-dimethylselenopseudourea hydroiodide (3), 1,2,3,4-tetra-O-acetyl-6-S-dimethylarsino-6-thio-beta-D-glucopyranose (4), 1,2,3,4-tetra-O-acetyl-6-Se-dimethylarsino-6-seleno-beta-D-glucopyranose (7), 6-S-dimethylarsino-6-thio-beta-D-glucopyranose (5), and 6-Se-dimethylarsino-6-seleno-beta-D-glucopyranose (9) are described. Various spectral properties of the compounds are given. The relative rates of alkaline hydrolysis of 5 and 9 are compared.
