butenolides has been established based on Sharpless asymmetric dihydroxylation in high yields and good enantiopurity. The route could be expanded to the synthesis of α,γ-disubstituted butenolide units of naturally occurring annonaceous acetogenins. Utilizing this strategy, three simple natural products with butenolide segments were synthesized enantioselectively.
