✦ Synopsis

Many new cyclic esters of N-toluenesulfonyl ␣-aminophosphonic acids were synthesized by the three-component reaction of p-toluenesulfonamide, an aromatic aldehyde, and 2-chloro-1,3,2-benzodioxaphosphole in anhydrous benzene. Different reaction conditions have been investigated, and the related reaction mechanisms have been suggested.
