A new synthesis of 1,3-difunctionalized 2-sulfonamidopropane derivatives via regioselective ring opening reactions of 2-(bromomethyl)-1-sulfonylaziridines by substituted arylsulfonamides

The novel functionalized N,N′-[2-(arylsulfonamido)propane-1,3-diyl]bis(N-allylarylsulfonamide) and N,N′-[2-(methylsulfonamido)propane-1,3-diyl]bis(N-benzylarylsulfonamide) derivatives have been prepared from 2-(bromomethyl)-1-sulfonylaziridines for the first time using substituted arylsulfonamides in the presence of sodium methoxide under catalyst-free condition in good yields.
