Cholinesterases, carbonic anhydrase inhibitory properties and in silico studies of novel substituted benzylamines derived from dihydrochalcones

, 2021
A series of novel urea, sulfamide and N,N-dipropargyl substituted benzylamines were synthesized from dihydrochalcones. The synthesized compounds were evaluated for their cholinesterases and carbonic anhydrase inhibitory actions.

Pyridine‐2‐Sulfinate as a Bifunctional SO2 Transfer Reagent; Unlocking Structurally Diverse, Ortho‐Functionalized Masked Sulfinates

Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
The commercially available 2‐pyridyl “Willis’ sulfinate” is demonstrated as an efficient SO2 transfer reagent (STR) providing single‐step access to a 2‐pyridyl masked sulfinate from (hetero)aryl bromides and iodides. Following installation, the pyridyl auxiliary delivers ortho‐selective functionalization via chelate‐assisted CH activation, providing a ...
