First enantioselective synthesis of (+)-quinolizidine : determination of the absolute stereochemistry

First enantioselective synthesis of quinolizidine 207I has been achieved and the absolute stereochemistry of natural quinolizidine 207I was determined to be 1S,4S,10S by the present chiral synthesis using GC analysis with β-dextrin chiral column on co-injection with racemate.
