Suzuki—Miyaura Cross-Coupling of 3-Pyridyl Triflates with Alk-1-enyl-2-pina-col Boronates. — The title reaction proceeds smoothly providing the cross-coupled products (III) in moderate to good yields. Also, the cross-coupling reaction is carried out with the more functionalized alkenyl boronate (VI) towards a convergent synthesis of cananodine. Compound (VII) contains all of the carbon atoms necessary for the syn-thesis of the bicyclic core of cananodine. Diene (IIIb) represents a reasonable precursor for the preparation of xestamine C. — (VYVYAN*, J. R.; DELL, J. A.; LIGON, T. J.; MOTANIC, K. K.; WALL, H.
