Stereoinversion of Unactivated Alcohols by Tethered Sulfonamides.

open access: yesAngewandte Chemie, 2019
The direct, catalytic substitution of unactivated alcohols remains an undeveloped area of organic synthesis. Moreover, catalytic activation of this difficult electrophile with predictable stereo-outcomes presents an even more formidable challenge ...

Design, synthesis, and biological evaluation of novel N4-substituted sulfonamides: acetamides derivatives as dihydrofolate reductase (DHFR) inhibitors

open access: yesBMC Chemistry, 2019
BackgroundSulfonamide derivatives are of great attention due to their wide spectrum of biological activities. Sulfonamides conjugated with acetamide fragments exhibit antimicrobial and anticancer activities.

A Scaffold‐Diversity Synthesis of Biologically Intriguing Cyclic Sulfonamides

open access: yesChemistry, 2019
A “branching–folding” synthetic strategy that affords a range of diverse cyclic benzo‐sulfonamide scaffolds is presented. Whereas different annulation reactions on common ketimine substrates build the branching phase of the scaffold synthesis, a common ...

Sulfonamides in the environment: a review and a case report

open access: yes, 2018
Sulfonamides are widely used in treatment of animals and humans but pose a risk as environmental pollutants. An analysis of 1588 publications focused on sulfonamides is presented here.
