A highly stereoselective approach to (-)-2-epilentiginosine and (+)-lentiginosine has been developed based on a diastereofacially selective cycloaddition of dichloroketene with a chiral dienol ether. The two naturally occurring indolizidines are each obtained enantioselectively (≥ 99:1) in ca. 8.5% overall yield.
