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.

Stanovnik, B.,Tisler, M.,Golob, V.,Hvala, I.,Nikolic, O.
, p. 733 - 736 (2007/10/02)
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.
