The solvolytic behavior of 3-ethoxycarbonyl-2-phenyl-Δ2-4,5-diones 7 depends on the N-substituents.On treatment with ethanol or methanol, the NH derivative 7a afforded the corresponding keto ester 9, a product of C5-lactam carbonyl a
FACILE OXY-VINYL SHIFT PROMOTED BY TETRABUTYLAMMONIUM FLUORIDE: A HYDROINDOLE SYNTHESIS
Sano, Takehiro,Toda, Jun,Tsuda, Yoshisuke

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
