Two different ways to carry out the chemoselective acylation of 2-amino-8-quinolinol with unique features to generate C2-amides or C8-esters were developed. The coupling reaction with a variety of carboxylic acids using EDCI and DMAP provided C8-ester derivatives, whereas N-heteroaromatic acids were not introduced on the C8-hydroxy group, but rather on the C2-amino group under the same conditions. To obtain C2-amides selectively, the anionic nucleophile from 2-amino-8-quinolinol was treated with less reactive acyl imidazolides or esters.

The reactions of 2-amino-8-hydroxyquinoline and 2-amino-4(1H)quinolone with different sulfonyl chlorides have been investigated. The chemoselectivity was observed to afford exclusively the arylsulfonate ester derivatives. The mechanism of the reaction is
