azaheterocycle N-oxides with alkenes catalyzed by iodine under metal- and external oxidant-free reaction conditions has been developed. A variety of (E)-2-styrylazaheterocycles have been produced in moderate to excellent yields. The mechanistic exploration indicated that the N-oxide group played dual roles as both the directing group and an internal oxidant in this catalytic cycle.

The present invention provides for 8-hydroxy-7-substituted quinoline compounds such as formula III
These compounds are useful as anti-viral agents. Specifically, these compounds have anti-viral activity against the herpes virus, cytomegalovirus (CMV). Many of these compounds are also active against other herpes viruses, such as the varicella zoster virus, the Epstein-Barr virus, the herpes simplex virus and the human herpes virus type 8 (HHV-8).
describes the synthesis of 2-phenylvinylquinoline (styrylquinoline) and 2-furanylvinylquinoline derivatives and evaluation for their antiproliferative activities. (E)-2-Styrylquinolin-8-ol (14a) was inactive against a 3-cell line panel consisting of MCF-7 (Breast), NCI-H460 (Lung), and SF-268 (CNS). Replacement of the phenyl ring with 5-nitrofuran-2-yl group significantly enhanced antiproliferative activity

The design and synthesis of a newclass of chiral quinoline–phosphine ligands has been achieved. Their efficiency as asymmetric ligands in enantioselective palladium-catalyzed allylic substitution reactions and in the asymmetric copper-catalyzed addition of diethylzinc to enones was also investigated.
