AbstractAn efficient strategy for the synthesis of a variety of 3‐methyleneisoindolin‐1‐ones has been developed. The reaction proceeded from coupling of 2‐iodobenzamides (or 2‐bromobenzamides) and terminal alkynes via Cu(OAc)2·H2O/2,2′‐biimidazole catalyzed in DMF at 60°C and subsequent additive cyclization produced substituted 3‐methyleneisoindolin‐1‐ones in good to excellent yields.

The ability of organoselenium molecules to mimic the activity of the antioxidant selenoenzyme glutathioneperoxidase (GPx) allows for their use as antioxidant or prooxidant modulators in several diseases associated with the disruption of the cell redox homeostasis. Current drug design in the field is partially based on specific modifications of the known Se-therapeutics aimed at achieving more selective
