Abstract
A palladium-catalyzed highly 6-endo-selective alkyl-Heck reaction of unactivated alkyl iodides provides efficient access to various 5-phenyl-1,2,3,6-tetrahydropyridine derivatives, which are important structural motifs for bioactive molecules. Mechanistic investigations reveal a hybrid palladium-radical process.
