The synthesis of dendrobatid alkaloid (+)-167B and (+)-209D has been developed on the basis of the effective preparation of chiral tropinone 7-azabicyclo[3.2.1]octan-6-ol. DFT calculations have been applied to explain the observed diastereoselectivity.
Enantiomeric syntheses of (â)-homopipecolic acid and (â)-pelletierine have been achieved by chiral resolution of tropanol followed by BaeyerâVilliger oxidation. The methodology provides a practical route for the synthesis of optically pure piperidines.
