Titanium(IV)-Promoted Regioselective Nucleophilic Ring-Opening Reaction of Chiral Epoxyallyl Alcohols with Acids as a Tool for Ready Access to Chiral 1,2,3-Triol Monoesters: Application to Stereoselective Total Synthesis of Macrolides
摘要:
Titanium(IV)-promoted regioselective ring-opening reaction of chiral epoxy-allyl alcohols (Sharpless conditions as the key strategic step) is developed as a tool for ready access to chiral 5,6-dihydroxyoct-7-en-4-yl alkoxylates. Later, the synthetic utility of products thereof was demonstrated through the RCM based stereoselective synthesis of various natural products.
