Microwave-Assisted Synthesis of Chiral Nopinane-Annelated Pyridines by Condensation of Pinocarvone Oxime with Enamines Promoted by FeCl3and CuCl2
摘要:
Reaction of pinocarvone oxime with enamines and FeCl3 or CuCl2 resulted in annulation of nopinane carbon frame with pyridine and regioselective formation of chiral nopinane-annelated pyridines in 20-39% yields. Chemical structure of the pyridine derivatives were proved by precise NMR study.
