✦ Synopsis

Total Syntheses of (±)-Cryptopleurine, (±)-Antofine, and (±)-Deoxypergularinine.

-Synthesis of cryptopleurine (X), antofine (VIIa), and deoxypergularinine (VIIb) emphasizes the synthetic potential of enecarbamates (III) and (IX). These key intermediates are of interest for the preparation of other naturally occurring phenanthroquinolizidine and -indolizidine alkaloids as well as their biogenetically related congeners. -(LEBRUN, STEPHANE;
