Novel synthetic method for allylic amination of cyclic allylic ethers using chlorosulfonyl isocyanate

The introduction of amines to allylic or benzylic position of cyclic compounds with chlorosulfonyl isocyanate is developed in high to excellent yields. This method provides a novel access to biologically active compounds including the framework of 1-aminoindanes, 1-aminotetralines, and 1-amino-2-hydroxy cyclic compounds. Mechanistic evidence for the reaction pathway is also provided.
