1,3-Dibromo-5,5-dimethylhydantoin (DBH) as an efficient promoter for acetylation of 3-arylsydnones in the presence of acetic anhydride under neutral conditions
TL;DR: In this article, 1,3-Dibromo-5,5-dimethylhydantoin (DBH) was found to efficiently promote the conversion of various 3-arylsydnones to their 4-acetyl congeners in the presence of acetic anhydride under neutral conditions in satisfactory yields.

Pd-catalyzed oxidative coupling of monosubstituted sydnones and terminal alkynes
TL;DR: The Pd-catalyzed oxidative coupling of N-substituted sydnones and terminal alkynes offers a quick, one-step synthesis of 4-alkynylsydnones in moderate to good yields.
Journal ArticleDOI
Straightforward Access to the Nitric Oxide Donor Azasydnone Scaffold by Cascade Reactions of Amines
TL;DR: A novel one-pot cascade method for the assembly of valuable NO-donor azasydnone scaffold provides a new approach to nitrogen-oxygen heterocycles with potential applications in medicine and material science.

Metal Ion Dependent Binding of Sulphonamide to Carbonic Anhydrase
TL;DR: The direct demonstration that binding of acetazolamide to human carbonic anhydrase requires the presence of a metal ion at the active site and that binding depends on the species of divalent metal ion present is reported.
