The S N2' reaction of propragyl mesylates with organozinc reagents was dramatically improved in DMSOsolvent, and the stereoselective conversion of chiral substrates was successfully achieved using LiCl-free diorganozinc without the loss of optical purity.

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.
