Tri- and tetrasubstituted 1,4-dien-3-ones 1 were treated with Lewis acid in the presence of triethylsilane, furnishing either silyl enol ethers 4 or cyclopentanones 5 in good yields, depending upon work-up conditions. This reaction is presumed to occur th
A NEW APPROACH TO CYCLOPENTANE ANNULATED COMPOUNDS VIA 1-(CYCLOPENT-1-ENYLCARBONYL)VINYLPHOSPHONATES, AND SYNTHESIS AND SYNTHETIC APPLICATION OF α-DIETHOXYPHOSPHORYL-Δα,β-BUTENOLIDES
