T1  - alpha,beta-Unsaturated delta-Valerolactones through RCM-Isomerization Sequence
JF  - Synlett : accounts and rapid communications in synthetic organic chemistry
N2  - alpha,beta-Unsaturated d-lactones are accessible via a sequential ring-closing metathesis (RCM) double-bond migration reaction starting from butenoates of allyl alcohols. This approach proceeds efficiently with lower catalyst loadings and higher initial substrate concentrations compared to the alternative RCM of acrylates derived from homoallylic alcohols.
