N-acylation of substituted sulfonamides with different anhydrides in the presence of Cesium salt of Wells–Dawson heteropolyacid (Cs5HP2W18O62) as an efficient and reusable catalyst was investigated for the first time. ?Cs5HP2W18O62 was used with a catalytic amount in water as a green solvent. At room temperature, a series of N-acylsulfonamides were synthesized, while under refluxing conditions, new cyclic imides containing sulfonyl group were obtained. Atom-economy, high yields, easy work-up, as well as simple catalyst recovery and reusability are the key features of this procedure.

A regioselective phosphonylation of quinolines for the synthesis of α-amino quinolinyl phosphonamides and γ-amino quinolinyl phosphonamides has been developed under mild reaction conditions. An NHP-thiourea enables selective synthesis of α-amino quinolinyl phosphonamides by a Reissert-type reaction, and an NHP-tosylamide affords γ-amino quinolinyl phosphonamides via a 1,4-conjugate addition reaction. The corresponding amino quinolinyl phosphonate adducts were obtained in moderate to excellent yields (up to 99% yield) and regioselectivities (up to 99:1) with good functional group tolerance.

Two series of new 5-benzylidenethiazolidine-2,4-diones bearing benzenesulfonamide moiety were designed and synthesized. The synthesized compounds were evaluated for several biological activities, including cytotoxicity, histone deacetylation, and protein
LUMINESCENT MACROCYCLIC LANTHANIDE COMPLEXES
-
Page/Page column 76, (2008/12/05)
The present invention provides a novel class of macrocyclic compounds as well as complexes formed between a metal (e.g., lanthanide) ion and the compounds of the invention. Preferred complexes exhibit high stability as well as high quantum yields of lanthanide ion luminescence in aqueous media without the need for secondary activating agents. Preferred compounds incorporate hydroxy-isophthalamide moieties within their macrocyclic structure and are characterized by surprisingly low, non-specific binding to a variety of polypeptides such as antibodies and proteins as well as high kinetic stability. These characteristics distinguish them from known, open-structured ligands.
Zirconium tetrachloride mediated regioselective transformation of N-tosylaziridines into β-chlorosulfonamides

, p. 82 - 83 (2008/09/21)
Regioselective ring opening of N-tosylaziridines has efficiently been carried out with ZrCl4 at room temperature to afford the corresponding β-chlorosulfonamides in high yields within a short reaction time.
