Dioxopyrroline. L. Skeletal rearrangements of 7-vinyl-7-trimethylsilyloxy-5-ethoxycarbonyl-1-phenyl-2-azabicyclo[3.2. 0]heptane-3,5-diones under thermal, basic, and acidic conditions

The oxyvinylcyclobutanes (2), photoadducts of the dioxopyrrolines (1) to trimethylsilyloxybutadienes, undergo two different types of skeletal rearrangements depending on the reaction conditions. Thermolysis of 2 caused expansion of the cyclobutane ring by
