Total synthesis of (±)-quinolizidine 207I, an alkaloid from Mantella baroni, a Madagascan mantelline frog
Abstract
The first synthesis of quinolizidine 207I was achieved by a totally stereocontrolled approach starting from a 9-azabicyclo[3.3.1]nonane derivative, thus establishing the exceptional axial stereochemistry of the ethyl group at position 1.
