(I) The novel compounds, stereoisomers thereof or pharmaceutically acceptable salts thereof according to the present invention have histone deacetylase (HDAC) inhibitory activity and are effective for the prevention or treatment of HDAC6-mediated diseases.
Low catalyst loadings for ligand-free copper(I)-oxide-catalyzed N-arylation of methanesulfonamide in water

A simple and practical protocol for the cross-coupling of methanesulfonamide and aryl iodides under ligand-free copper(I)-oxide-catalyzed conditions in water is reported. The method allows the preparation of a wide variety of synthetically useful N-arylated methanesulfonamides in good to excellent yields (up to 90 %) under the optimized conditions. A convenient and efficient ligand-free method using a copper(I) oxide catalyst at 130 °C in water was developed for the N-arylation of methanesulfonamide with aryl iodides. A variety of functionalized aliphatic and cyclic sulfonamides were coupled with different substituted aryl halides to give the corresponding N-arylated products in good to excellent yields under the optimized conditions.
