## Abstract We have investigated 1,5‐electrocyclic ring‐closure reactions of conjugated esters with dimethyl diazomalonate in the presence of [Cu(acac)~2~] as catalyst. Our new protocol offers an easy entry to various polyfunctionalized __γ__‐lactones in high yields. Their subsequent derivatives ma
