Small amounts of n-butyllithium catalyse the highly efficient hydroamination of a large variety of vinylsulfides. This novel methodology offers an easy access to a wide range of nitrogen heterocycles, including simple pyrrolidines and piperidines, as well as more complex bicyclic compounds. Subsequent transformations of the sulfur group led to the formation of functionalised alkaloid-like substructures
