(+)-jasplakinolide is described. The synthesis of the polyketide template utilized a diastereoselective syn-aldol, ortho-ester Claisen rearrangement followed by efficient conversion to a cyanide. The beta-amino acid unit was constructed in a highlydiastereoselective manner utilizing nucleophilic addition to a chiral sulfinimine. Yamaguchi macrocyclization and removal of the protecting group provided
