Three-Component, Stereoselective Palladium-Catalyzed Synthesis of FunctionalBicyclopentanoids. — Cyclooctadiene (I) is shown to undergo a palladium-cata10- 059 ized
lyzed stereoselective reaction which leads to the substituted bicyclo[3.3.0]octane endo-exo system. In a single step the reaction transforms three simple starting materials
into a functionalized complex product, forming three carbon-carbon bonds and fixing
four stereogenic centers with complete selectivity. The reaction affords a bis- endo adduct when carried our in an oxygen atmosphere. — (HULIN*, B.; NEWTON, L. S.;
