Divergent Route to Access Structurally Diverse 4-Quinolones via Mono or Sequential Cross-Couplings
摘要:
A divergent route was developed to access 3-iodo- and 6-chloro-3-iodo-4(1H)-quinolones for further elaboration via mono and/or sequential Suzuki-Miyaura cross-coupling to generate novel and medicinally important 4(1H)-quinolones. Copper- and palladium-catalyzed cyanations were used to functionalize the 4-quinolone core further.

An efficient one-pot synthesis of indanone fused heterocyclic compounds via SeO2/FeCl3 promoted intramolecular Friedel-Craft acylation reaction
for generating indanone fused heterocyclic compounds which contains a unique tetracyclic isoflavone moiety was developed. This unprecedented one-pot route utilizes a wide spread of substrates through three-step tandem Riley oxidation/Friedel-Crafts reaction/oxidation with SeO2/FeCl3 in moderate yield. Moreover, some of the synthesized heterocyclic compounds have shown moderate anticancer activities
