N-(Phenylsulphonyloxy)quinolinimide (I) reacts with different nucleophiles to give II-VIII.It was proved that the nucleophilic attack occurs at the more electro-positive carbonyl group to give only one product in good yields.

The possibility of formation of substituted heterocyclic amides from heteroacyl azides and aromatic or heteroatomic amines was investigated.Although acylation proceeded in some cases under mild reaction conditions, formation of N,N'-disubstituted ureas was the main process at elevated temperatures.
