The ability to detect and quantify polymorphism of pharmaceuticals is critically important in ensuring that the formulated product delivers the desired therapeutic properties because different polymorphic forms of a drug exhibit different solubilities, stabilities and bioavailabilities. The purpose of this

The first catalytic asymmetric synthesis of β-sultones is reported. This development has enabled a rapid access to a number of highly enantioenriched biologically interesting sulfonyl and sulfinyl compound classes, which makes use of the inherent ring strain of the four-membered

A density functional theory investigation was carried out to characterize (14)N electric field gradient tensors, EFG, in crystalline sulfamerazine and sulfathiazole. To include hydrogen-bonding effects in the calculations, the most probable interacting molecules with the target were considered as tetrameric

A phosphine-mediated one-step disulfide formation from S-nitrosothiols has been developed. This reaction can convert unstable S-nitrosothiols to stable disulfides via sulfenamide intermediates under very mild conditions. It has the potential to be used for the detection of S-nitrosothiols.
