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

FACILE OXY-VINYL SHIFT PROMOTED BY TETRABUTYLAMMONIUM FLUORIDE: A HYDROINDOLE SYNTHESIS

The oxy-vinyl alkoxides generated from trimethylsilyloxy-vinyl (or methoxyvinyl)-cyclobutanes by tetra-n-butylammonium fluoride undergo a facile shift to produce a two-carbon unit ring expansion compound under extremely mild conditions.Thus, 7-trimet
