The synthesis of functionalized nine-membered ring lactones based on sequential esterification and ring-closingmetathesis (RCM) reactions is reported. The effects of olefin substitution and allylic and homoallylic oxygenated substituents on the RCMreaction is analyzed. An unusual cyclization stereochemistry has been observed, leading to a stereoselective olefin formation in the synthesis of nonanolactones
