Abstract
The application and versatility of 2-fluoro-1-methylpyridinium p-toluenesulfonate as acid activator in the synthesis of several β-lactams under mild reaction conditions by use of ketene–imine cycloaddition reactions has been investigated. The effects of solvents, molar ratio of reagents, and temperature were considered. The method was also used for preparation of β-lactams substituted in position 3 by electron-withdrawing groups. The products are obtained in good to excellent yields.Graphical Abstract.
