摘要

A series of bicyclic pyridine containing alkaloids related to (−)-cytisine and varenicline are described. Synthetic access via regioisomeric metalation of alkoxy-and halo-pyridines gains entry to all four isomeric [3.3. 1]-bicyclic targets. Regioselective and sequential oxidative cleavage of dicyclopentadiene generates a related [3.2. 1]-bicyclic analog.
