Chemistry in the Ambient Field of the Alkaloid Epibatidine. Part 2. Triphenylarsine as an Efficient Ligand in the Pd-Catalyzed Synthesis of Epibatidine and Analogues.
-Triphenylarsine is found to be more efficient than triphenylphosphine in the Pd-catalyzed coupling of bicyclic alkenes (I) with pyridine derivative (II). A chiral version of the reaction gives the N-protected epibatidine (IIIa) in high yield, but only low asymmetric induction.
