- Direct syntheses of polyfused ring systems by intramolecular tandem palladium-ene/Heck insertion reactions
Oppolzer, W.; DeVita, R. J.
J. Org. Chem. 1991, 56, 6256-6257
The Pd(0)-catalyzed polycyclizations 1 → 3 + 4, 5 → 9 and 6 → 10 are described. The stereospecifity of these transformations is ascribed to an intramolecular suprafacial “palladium-ene” process followed by one to two “Heck-insertions” proceeding with retention of configuration at the metalated carbon.
