2,5-BIS(METHOXYCARBONYL)-3,4-DIPHENYLCYCLOPENTADIENONE Chemical Properties,Usage,Production
Uses
2,5-Bis(methoxycarbonyl)-3,4-diphenylcyclopentadienone is used a reagent for cycloaddition reactions.
Preparation
Preparative Method of 2,5-Bis(methoxycarbonyl)-3,4-diphenylcyclopentadienone: equimolar amounts of benzil and dimethyl 2-propanone-1,3-dicarboxylate in MeOH or EtOH with OH- are allowed to react at 25 °C for 1 day to give the intermediate dimethyl 3,4-diphenyl-4- hydroxycyclopent-2-enone-2,5-dicarboxylate in 70-96% yield. Treatment of the intermediate with acid in benzene or in Ac2O with heating gives the dienone in 98% yield containing 3% of the Diels-Alder dimer[1-2].
