The regiospecific N-sulfonylation and N-phosphorylation of benzoyl-substituted heterocyclic ketene aminals have been investigated. In the presence of sodium hydride, benzoyl-substituted heterocyclic ketene aminals 1 or 2 reacted with p-toluenesulfonyl chloride 3 to give (E)-1-(p-toluenesulfonyl)-2-(
