Guillier, F. published the artcileCombined Metalation-Palladium-Catalyzed Cross Coupling Strategies. A Formal Synthesis of the Marine Alkaloid Amphimedine, Name: (2-Pivalamidophenyl)boronic acid, the publication is Journal of Organic Chemistry (1995), 60(2), 292-6, database is CAplus.
The synthesis of 5-(4-pyridyl)benzo[c][2,7]naphthyridin-4-one (I), an intermediate previously employed in a total synthesis of the marine alkaloid, amphimedine (II), is reported. The route comprises the Pd-catalyzed Suzuki cross coupling of a pyridylborane with 2-iodoaniline to give the azabiaryl III, which upon LDA-mediated cyclization and triflation leads to benzonaphthyridine IV. Stille cross coupling of IV with a pyridylstannane affords the pyridylbenzonaphthyridine, which upon BBr3 treatment leads to I.
