Synthesis of S-glycosyl primary sulfonamides.
The synthesis of S-glycosyl sulfonamides wherein the primary sulfonamide functional group (-SO(2)NH(2)) is directly attached to the anomeric position of a carbohydrate moiety is reported. Our general approach consists of first introducing a thioacetate group at the anomeric center of a per-O-acetylated sugar derivative. From this follows formation of a glycosyl sulfenamide (sugar-SNR(2)), oxida...
متن کاملRegioselective Annulation of Aryl Sulfonamides with Allenes through Cobalt-Promoted C-H Functionalization.
The development of an efficient method for the construction of biologically relevant sultams is described, which represents the first case of cobalt-promoted C-H/N-H functionalization of sulfonamides with allenes. This newly developed annulation reaction demonstrated good functional group tolerance and excellent regioselectivity. Both terminal monosubstituted allenes and internal disubstituted ...

CLINICAL VIGNETTE A 48-year-old man was referred to our clinic with high-grade intermittent fever for 8 days and a generalized rash for 3 days. Threeweeks before presentation, the patient had been started on 5 mg/d prednisolone, 50 mg of diclofenac twice daily, 20 mg/d omeprazole, and 2 g/d of sulfasalazine for symptomatic ankylosing spondylitis. During the initial evaluation, he was febrile (3...
متن کاملOral Antidiabetic Sulfonamides
In October 1955 three reports in the Deutsche Medizinische Wochenschrift' described a new sulfonamide derivative possessing the ability when given by mouth to reduce normal blood sugar values to subnormal, and elevated blood and urine sugar values in diabetes to normal. Reduction of normoglycemia had been shown with other sulfonamide derivatives as early as 1942," but the application to therapy...
