allylic alcohol formation of dialkyl alkylidenesuccinates has been demonstrated to accomplish one-step syntheses of several essential butenolides and fused butenolidesvia an unusual E- to Z- carbon–carbon double bond isomerisation followed by the lactonization pathway. The observed regio- and stereoselective SeO2 allylic oxidation protocol has also been extended to the diastereoselective total synthesis
