Synthesis of Optically Active .alpha.-Hydroxy Lactones by Sharpless Asymmetric Dihydroxylations of Ketene Acetals, Enol Ethers, and Ene Lactones
摘要:
Three different AD routes to optically active alpha-hydroxy lactones of good to excellent optical purity are reported. The substrates for the AD reaction are endocyclic ketene acetals, endocyclic enol ethers, and exocyclic alpha,beta-unsaturated lactones.
