The present invention relates to antimalarial compounds. More specifically, the present invention relates to novel substituted quinolone derivatives of formula (I) and related quinoline derivatives of formula (II) as defined herein that possess potent antimalarial activity. The present invention also relates to processes for the preparation of these quinolone and quinoline derivatives, to pharmaceutical compositions comprising them and to their use as therapeutic agents for the treatment and/or prevention of malaria.
Reaction of diazonium salts with transition metals. 6. Preparation of mixed acid anhydrides from arenediazonium salts and sodium carboxylates under palladium(0) catalysis
Palladium catalyzed reaction of arenediazonium salts, carbon monoxide and sodium carboxylates gave mixed anhydrides, which in turn could be converted to aromatic acid anhydrides in good yields.
