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

2-AZABICYCLOHEPTANE-3,4-DIONES (6) A NOVEL METHOD OF REGIO-CONTROLLED SYNTHESIS OF FUNCTIONALIZED HYDROINDOLES AND ERYTHRINAN DERIVATIVES

A regio-controlled synthesis of functionalized hydroindoles from a Δ2-pyrrolinedione and its application to the synthesis of erythrinan skeleton were described.The method is to construct with photocycloaddition of a trimethylsilyloxybutad
