Acetal-protected (2,4-dioxocyclohex-1-yl)acetic acid derivatives were prepared by the allylation of dilithiated 1,3-cyclohexane-1,3diones, by the protection of the carbonyl groups and by the oxidation of the alkene. The products were then transformed, by amide formation and subsequent cyclization, i
The reactive 1:1 intermediate obtained from the addition of triphenylphosphine to dibenzoylacetylene was trapped by heterocyclic NH-acids such as imidazole, 4-nitroimidazole, or 5-methyl-4-nitroimidazole to produce 2,3,5-trisubstituted furan derivatives. Using 2-benzoylimidazole or saccharin as NH-a
