Synthesis of (E)-β-Selenovinyl Sulfones through a Multicomponent Regio- and Stereospecific Selenosulfonation of Alkynes with Insertion of Sulfur Dioxide

A novel and practical method for the selenosulfonation of alkynes with the insertion of sulfur dioxide has been developed. A series of β-(seleno)vinyl sulfones with high levels of regio- and stereoselectivity have been prepared. The key features of this reaction include a broad substrate scope, excellent functional-group tolerance, and amenability to scale-up synthesis. A plausible radical mechanism is proposed to illustrate this reaction.

Copper-Catalyzed Three Component Regio- and Stereospecific Selenosulfonation of Alkynes: Synthesis of (E)-β-Selenovinyl Sulfones

A copper-catalyzed highly regio- and stereospecific selenosulfonation of alkynes with arylsulfonohydrazides and diphenyl diselenide has been developed. This novel three component reaction proceeds under very mild conditions and with a broad scope of substrates, providing a wide range of (E)-β-selenovinyl sulfones in good to excellent yields.

Solid-phase synthesis of β-keto sulfones

A novel method for the preparation of β-keto-sulfones through the use of organoselenium reagents in the solid phase by polystyrene-supported benzeneselenosulfonate or tolueneseleno-sulfonate with acetylenes has been developed. Georg Thieme Verlag Stuttgart.
