Synthesis of 2-alkenyl-3-(alkoxycarbonyl)furans based on Feist-Benary cyclocondensation of (2,4-dioxobutylidene)phosphoranes with alpha-haloketones and alpha-chloracetaldehyde.
3-Acyl-2-alkenylfurans were prepared by "Feist-Benary cyclocondensation" of (2,4-dioxobutylidene)phosphoranes with chloracetaldehyde and alpha-haloketones and subsequent Wittig reactions.
