A route to enantiomerically enriched γ-lactones α,β-fused to medium-sized rings LA - eng PY - 2004 SP - 4787 EP - 4789 T2 - Organic Letters SN - 1523-7060 VL - 6 IS - 25 AB - (Chemical Equation Presented) The stereoselective alkylation of α(phenylsulfonyl)-β-[(methoxycarbonyl)methyl]-γ-lactones obtained by the base-induced cyclization of enantiomericaily enriched α-[(phenylthio)acyl]-α,β-unsaturated esters and ring-closing olefin metathesis (RCM) are the basis of a new approach for gaining access to γ-lactones that are α,β-fused to medium-sized carbocycles and cyclic ethers.
