Abstract
A condensation-cycloaddition-cross-coupling reaction sequence has been applied to the synthesis of phenanthridone derivatives. This novel two-step procedure is based on a three-component reaction to give 2-halobenzamide-substituted cyclohexenes, which undergo palladium-catalyzed intramolecular Heck cyclizations.
Key words
domino reactions - Heck reactions - isomerizations - heterocycles - palladium

15 X-ray data of 10a were collected with a STOE-IPDS diffractometer using graphite-monochromated Mo-K
α radiation (λ = 0.71069 Å). The structure was solved by direct methods
