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.

Asymmetric syntheses of biologically and pharmaceutically important (-)-hygroline, (-)-pseudohygroline, and (-)-hygrine were achieved by a newly developed 'N-methylative aziridine ring opening reactions' of (2S)-methoxycarbonylethylaziridine as a key step. (C) 2014 Elsevier Ltd. All rights reserved.
