A series of novel 9-O-substituted-berberine derivatives were synthesized and their anti-inflammatory activities were evaluated. Among them, compounds 3i and 5e exhibited excellent anti-inflammatory potential.

A palladium/norbornene-catalyzed vicinal difunctionalization of enol triflates has been developed for rapid, modular and regioselective synthesis of multisubstituted acrylamides from simple ketones. The reaction exhibits broad functional group tolerance, and the use of bulky secondary amide-derived norbornenes appears to be a key parameter to maintain high efficiency and selectivity.
