2,3-bis(acetoxymethyl)bicyclo[2.2.1]hepta-2,5-diene 1 undergoes nucleophilic attack of secondary amines under catalyzed Pd(0) reaction conditions. The influence of various tertiary amines as acceptor bases on the reaction as well as the nature of the organophosphorus ligands on the metal has been investigated. The use of chiral heterocyclic ligands led to the formation of the monoaminated product 2e with enantiomeric excess up to 89%.
