Abstract: Benzenesulfonylureas and -thioureas of the formula I where R(1) is H or (fluoro)methyl, R(2) is H, Hal or (fluoro) (mercapto)alk(oxy)yl, E is O or S; Y is —[CR(3)2]n—, where R(3)=H or alkyl and n=1-4, X is H, Hal or alkyl and Z is Hal, NO3 or alk(yl)oxy, are described. The compounds I are used for treatment of disturbances in cardiac rhythm and prevention of sudden cardiac death caused by arrhythmia, and can therefore be used an antiarrhythmics. They are particularly suitable for those cases where arrhythmias are a consequence of a narrowing of a coronary vessel, such as angina pectoris or acute cardiac infarction.

Abstract: Osmium-catalyzed methods of addition to an olefin are discussed. In the method of asymmetric dihydroxylation of the present invention, an olefin, a chiral ligand, an organic solvent, an aqueous solution, a base, a ferricyanide salt and an osmium-containing compound are combined. The chiral ligand is an alkaloid or alkaloid derivative linked to an organic substituent of at least 300 daltons molecular weight through a planar aromatic spacer group. The organic substituent can be another alkaloid or alkaloid derivative. With the described chiral ligands, asymmetric dihydroxylation of olefins with high yields and enantiomeric excesses are achieved.
