(1S,5S)-2-Azabicyclo[3.3.0]octane (1S,5S)-2 was synthesized from (1S,3S,5S)-2-azabicyclo[3.3.0]octane-3-carboxylic acid (1S,3S,5S)-1 in 84% yield by decarboxylation. The novel enantiomerically pure bicyclic pyrrolidine derivative (1S,5S)-2 was used as an efficient chiral auxiliary in Michael-type reactions via enamines.
