General description

4-Methoxybenzenesulfonamide, also known as p-methoxybenzenesulfonamide, is an aromatic sulfonamide. It can undergo polyaddition with vinyloxiranes in the presence of a palladium catalyst.

Application

4-Methoxybenzenesulfonamide may be used in the preparation of S,S-dimethyl-N-p-methoxybenzenesulfonylsulfilimine. It may also be used as a ligand to generate novel bis-tetrahydrofuran–based human immunodeficiency virus (HIV) protease inhibitor.
