The first enantioselective reductive Heck-type hetarylation of the azabicyclus 3 is presented using the optically active ligands 5-10. This asymmetric reaction provides both enantiomers of the protected trace alkaloid epibatidine in yields typically ranging from 30 to 60% with an enantiomeric excess up to 81%.
