摘要

6-Acylmino-1-alkyl/aryl-4-oxo-1, 4-dihydrocinnoline-3-carboxamides were synthesized in parallel from 6-nitro-4-oxo-1, 4-dihydrocinnoline-3-carboxylic acid. The latter formed amides with amines bound to polystyrene-based resins via acid-labile linkers. N1 and N2-alkylation, followed by alkyl migration yielded only N1-alkylated products. Reduction of the 6-nitro group and acylation concluded the synthesis.
