Synthesis of Novel 1-Hydroxyquinolones with High Anti-Toxoplasma Activity
摘要:
All for the treatment of malaria and toxoplasmosis the novel hydroxyquinolones 2-5 were prepared by reaction of aniline and hydroxyaniline, respectively and the beta-ketoesters 10a-c. As products the quinolones 8 and 15, respectively were obtained. Benzylation, oxidation and hydrogenation then led to the desired substances. Compound 2 has a similar anti-malaria activity as the approved drug Atovaquone.
