An enantioselective total synthesis of (+)-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 highly diastereoselective manner utilizing nucleophilic addition to a chiral sulfinimine. Yamaguchi macrocyclization and removal of the protecting group provided a convenient access to (+)-jasplakinolide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
