Unexpected S(O) 2 –O Bond Scission upon Anionic Cycliarylation of Cyclic Sulfamidates. A New Route to N-Functionalized Benzosultams.
Published: 19 October 2010 by MDPI in The 14th International Electronic Conference on Synthetic Organic Chemistry session General Organic Synthesis
Abstract: 1,2-Cyclic sulfamidates undergo novel, efficient and regiospecific intramolecular nucleophilic cleavage with aryllithiated species to provide an entry to poly, diversely and enantiopure N-substituted benzosultams.
Keywords: carbanion, anionic cyclization, sulfamidates, benzosultams.
