FeCl3-Diorganyl Dichalcogenides Promoted Cyclization of 2-Alkynylanisoles to 3-Chalcogen Benzo[b]furans
TL;DR: A general synthesis of 3-chalcogen benzo[b]furans from the readily available 2-alkynylanisoles, via FeCl(3)/diorganyl dichalcogenides intramolecular cyclization, has been developed and it is revealed that the reaction significantly depends on the electronic effects of substituents in the aromatic ring bonded to the selenium atom of the diselenide species.

TL;DR: The results suggest that the latency for the appearance of tonic-clonic seizures, characterized by rearing and falling of rat pups body, was dependent of the dose tested, and indicate the possible involvement of free radical oxygen injury in diphenyl diselenide-induced seizures.

Transmetalation of Z-telluroenynes: stereoselective synthesis of Z-enynols and their application in palladium-catalyzed cyclization.
TL;DR: The synthesis of various Z-enynols via reaction of vinyllithium intermediate with aldehydes and ketones is described and the subsequent cyclization of a wide variety of Z- enynols afforded substituted furans and dihydrofurans with high regioselectivity under mild reaction conditions.

Protective effect of unsymmetrical dichalcogenide, a novel antioxidant agent, in vitro and an in vivo model of brain oxidative damage.
TL;DR: Compound 3 protected against the increase in lipid peroxidation levels and the reduction of GST and GR activities in brain homogenate of mice exposed to SNP, suggesting the potential beneficial activity of dichalcogenides against deleterious oxidations in an in vivo model.

Highly Stereoselective One-Pot Procedure to Prepare Unsymmetrical Bis- and Tris-chalcogenide Alkenes via Addition of Chalcogens to Alkynes
TL;DR: The reaction of unsymmetrical diorganoyl dichalcogenides (RSe−SR1) with terminal alkynes under catalyst-free conditions, by a one-pot procedure, to prepare bis- and tris-chalcogenide alkenes selectively, avoiding the previous preparation of chalCogen alkynes.
