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

2-Aryl-3-ethoxycarbonyl-Δ2-pyrroline-4,5-diones (3) were easily prepared in good yields by condensation of enamino-esters (2) with oxalyl chloride.The products were characterized by ultraviolet and infrared spectroscopy.

FACILE OXY-VINYL SHIFT PROMOTED BY TETRABUTYLAMMONIUM FLUORIDE: A HYDROINDOLE SYNTHESIS
Sano, Takehiro,Toda, Jun,Tsuda, Yoshisuke
, p. 2960 - 2962 (2007/10/02)
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
2-AZABICYCLOHEPTANE-3,4-DIONES (1). A NOVEL EPIMERIZATION REACTION OF C7-SUBSTITUENTS.
Sano, Takehiro,Horiguchi, Yoshie,Tsuda, Yoshisuke
, p. 355 - 358 (2007/10/02)
On treatment with bases, 7,7-disubstituted and 7-substituted 2-azabicycloheptane-3,4-diones rapidly epimerized at C7 to give a thermodynamically more stable isomer (7-endo isomer in the cases of monosubstituted compounds) predominantly,
