A Concise Asymmetric Total Synthesis of (+)-Epilupinine

Asymmetric total synthesis of (+)-epilupinine was achieved in just 3 steps using only commercially available common reagents. The total synthesis involved alkylations of N-nosylamide, ozone oxidation, and sequential reactions of the removal of the nosyl group, intramolecular dehydrative condensation, intramolecular Mannich reaction catalyzed by L-proline, and a reduction.
