Ring-closing metathesis strategy to unsaturated γ- and δ-lactones: Synthesis of hydroxyethylene isostere for protease inhibitors

Ring-closing olefin metathesis of acrylates derived from allylic and homo allylic alcohols in the presence of the Grubbs' catalyst (10-15 mol%) and titanium isopropoxide (0.3-3 equiv) provided ready access to α, β- unsaturated γ and δ-lactones and an important dipeptide isostere intermediate.
