A three-component reaction of aryldiazonium tetrafluoroborates, sodium metabisulfite, and 3-azido-2-methylbut-3-en-2-ol under mild conditions is described. By using abundant and cheap sodium metabisulfite as the sulfur dioxide surrogate, this protocol features good functional group compatibility, affording 2-arylsulfonylacetonitriles in moderate to good yields. The reaction proceeds smoothly at room temperature without the need of any catalysts or additives. Moreover, the synthetic utility of this method is demonstrated by the transformation of 2-arylsulfonylacetonitrile into 2-arylsulfonyl acetamide and 2-arylsulfonylethylamine. (Figure presented.).

Metal-free insertion of sulfur dioxide with aryl iodides and 3-azido-2-methylbut-3-en-2-ol under ultraviolet irradiation at room temperature is achieved, giving rise to 2-(arylsulfonyl)acetonitriles in moderate to good yields. Alkyl iodide is also workable under these conditions. This transformation proceeds smoothly under mild conditions with a broad substrate scope. Various functional groups are compatible including amino, ester, halo, and trifluoromethyl groups. No metal catalyst or additive is needed during the reaction process. Mechanistic studies show that under ultraviolet irradiation, an aryl radical is generated in situ from aryl iodide, which undergoes subsequent sulfonylation via the insertion of sulfur dioxide leading to arylsulfonyl radical intermediates. Then the arylsulfonyl radical reacts with 3-azido-2-methylbut-3-en-2-ol giving rise to the corresponding 2-(arylsulfonyl)acetonitrile.

Urea transporters, which include UT-B in kidney microvessels, are potential targets for development of drugs with a novel diuretic ('urearetic') mechanism. We recently identified, by high-throughput screening, a triazolothienopyrimidine UT-B inhibitor, 1, that selectively and reversibly inhibited urea transport with IC50 = 25.1 nM and reduced urinary concentration in mice (Yao et al.J. Am. Soc. Nephrol., in press). Here, we analyzed 273 commercially available analogues of 1 to establish a structure-activity series and synthesized a targeted library of 11 analogues to identify potent, metabolically stable UT-B inhibitors. The best compound, {3-[4-(1,1-difluoroethyl)benzenesulfonyl]thieno[2,3-e][1,2,3]triazolo[1,5-a] pyrimidin-5-yl}thiophen-2-ylmethylamine, 3k, had IC50 of 23 and 15 nM for inhibition of urea transport by mouse and human UT-B, respectively, and ~40-fold improved in vitro metabolic stability compared to 1. In mice, 3k accumulated in kidney and urine and reduced maximum urinary concentration. Triazolothienopyrimidines may be useful for therapy of diuretic-refractory edema in heart and liver failure.

An efficient rhodium(I)-catalyzed addition of arylboronic acids to (benzyl-/arylsulfonyl)acetonitrile is described. Novel β-sulfonylvinylamine products are formed in a stereoselective fashion (Z-alkene). Upon hydrolysis, useful β-keto sulfones are obtained with a broad scope of aryl and sulfonyl substituents.
