Furan-2,3-diones as masked dipoles: synthesis of isotetronic acids and mechanistic considerations
Barbier, Vincent,Couty, Fran?ois,David, Olivier R.P.
, p. 5646 - 5651 (2016/08/17)
The formal dipolar behaviour of furan-2,3-diones is illustrated by their reaction with ethyl glyoxylate under Lewis basic activation uniquely, giving access to isotetronic derivatives. The Janus-type nature of the activated species, both nucleophilic and

The Wittig reaction of 5-aryl-furan-2,3-diones 1 with acylmethylenetriphenylphosphoranes 2 conducted by heating under reflux in benzene solutions, proceeded regiospecifically to afford 2-acylmethylene-5-aryl-3(2H)-furanones 5 in good yields. When the star
Synthesis and 13C FT NMR spectroscopy of furan-2,3-dione derivatives

Substituted furan-2,3-diones were obtained by condensation of oxalyl chloride with silyl enol ether of para-substituted acetophenones (R = H, CH3, OCH3, Cl, Br, F), propiophenone, 1-tetralone, 6-methoxytetralone and 1-benzosuberone.The spectroscopic data obtained from IR, UV, 1H and 13C NMR studies are quite similar whichever are the substituents. furan-2,3-dione / 1H and 13C NMR / UV and IR spectra
