Access to Saturated Thiocyano-Containing Azaheterocycles via Selenide-Catalyzed Regio- and Stereoselective Thiocyanoaminocyclization of Alkenes.

An efficient route for the synthesis of saturated thiocyano-containing azaheterocycles by selenide-catalyzed regio- and stereoselective thiocyanoaminocyclization of alkenes is disclosed. The desired products were obtained in moderate to high yields under mild conditions. The generality of this method was elucidated by its efficient application in thiocyano oxycyclization of alkenes.
