Heteroleptic nickel(II) complexes [NiL2L′] of a series of monoanionic and potentially bidentate N-2-pyridyl-sulfonamideligands [HL] and 2,2′-bipyridine or 1,10-Phenanthroline (L′) have been prepared by electrochemical oxidation of a nickel anode in an acetonitrile solution of the ligands. The complexes have been characterized by microanalysis, IR and electronic spectroscopy, magnetic measurements

a metal-free, environment-friendly photoredox-catalyzed sulfonylation of phenylhydrazines using thiols, employing MeCN:H2O as a green solvent and eosin Y as a photoredox catalyst. This strategy exhibits a broad substrate scope and good functional group compatibility, including hetero(aryl) as well as aliphatic phenylhydrazines. Finally, this protocol also demonstrated good application for the synthesis

A high-throughput screen targeting the EP1 receptor identified non-acidic glycine sulfonarnide derivative 2a with a pKi of 6.2. Analogue synthesis allowed a thorough investigation of the structure-activity relationship (SAR) and led to a 100-fold increase in recombinant potency. (c) 2006 Elsevier Ltd. All rights reserved.
