Enantioselective Synthesis of Jaspine B (Pachastrissamine) and Its C‐2 and/or C‐3 Epimers

Abstract Jaspine B and its C‐2 and/or C3 epimers have been enantioselectively prepared from butadiene monoepoxide through a synthetic procedure consisting of allylic amination by palladium‐catalyzed dynamic kinetic asymmetric transformation, cross metathesis, and stereoselective dihydroxylation as key steps.
