Tandem approaches for the synthesis of pyrrolidone precursor of allokainic acid and kainic acid are described. The synthesis of pyrrolidone intermediate of allokainic acid is achieved by tandem Wittig–Michael reaction and tandem amidation-Michael reaction while one pot amidation—Ene-esterification is employed for the synthesis of Ganem intermediate (2:1) of kainic acid.

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.
