Environmental Concentrations of Sulfonamides Can Alter Bacterial Structure and Induce Diatom Deformities in Freshwater Biofilm Communities

Frontiers in Microbiology, 2021
Since the early 1920s, the intensive use of antibiotics has led to the contamination of the aquatic environment through diffuse sources and wastewater effluents.

Acid-promoted dehydroxylation coupling of aryl alcohols with 1,3-dicarbonyls and sulfonamides [PDF]

BMC Chemistry
The formation of C–C and C–N bonds is an effective means to construct functional complex molecules. Herein, the TsOH-promoted dehydroxylation coupling of diarylmethanols with 1,3-dicarbonyls and sulfonamides to afford a variety of N-alkylated1,3 ...

Application of Micellar Mobile Phase for Quantification of Sulfonamides in Medicated Feeds by HPLC-DAD

Molecules, 2021
Rapid chromatographic procedure for quantification of five sulfonamides in medicated feeds are proposed. Satisfactory separation of sulfonamides from medicated feeds was achieved using a Zorbax Eclipse XDB C18 column (4.6 × 150 mm, 5 µm particle size ...

Photocatalytic Late-Stage Functionalization of Sulfonamides via Sulfonyl Radical Intermediates

ACS Catalysis, 2022
A plethora of drug molecules and agrochemicals contain the sulfonamide functional group. However, sulfonamides are seldom viewed as synthetically useful functional groups. To confront this limitation, a late-stage functionalization strategy is described,
