A general asymmetric route for the synthesis of the alexine and australine family of pyrrolizidine alkaloids. The first asymmetric synthesis of 1,2-diepi-alexine and 1,2,7-triepi-australine

The first asymmetric synthesis of 1,2-diepi-alexine and 1,2,7-triepi-australine (both are unknown at present) is described, which utilized the regioselective asymmetric aminohydroxylation (RAA) reaction of the achiral olefin VI, the cross metathesis (CM)
