Avenues to asymmetricalkaloids! Various 2‐substituted pyrrolidine and piperidine chiral bioactive natural products were synthesized using a ‘chiral pool’ method. l‐proline and l‐pipecolinic acids with one chiral center served as the best precursors for the synthesis of these alkaloids. Overall, 14 total synthetic and 11 formal synthetic approaches were developed.
