Cookson's pentacyclic cage diketones substituted with an electron-donating group (1b-e) underwent a remarkably fast cycloreversion reaction under various Lewis acid catalyzed conditions.The high reactivity of these cage ketones is discussed in terms of push-pull type interactions on the basis of large substituent effects and kinetic measurements.Keywords - cycloreversion reaction; Cookson's pentacyclic cage diketone; Lewis acid catalyst; electron-donating group; stereoelectronic effect
