Abstract

The addition of mono-and dianions of ethyl N-pivaloyl-3-aminocrotonate to substituted nitroarenes, followed by action of silylating or acylating agent, leads to 3-aminoquinoline carboxylic acid derivatives. Hydrolysis and decarboxylation of the latter, carried out efficiently under relatively mild conditions, afford 3-aminoquinolines diversely substituted in the benzo-fused ring.
