Synthesis of 2-Alkenyl-3-(alkoxycarbonyl)furans Based on Feist−Benary Cyclocondensation of (2,4-Dioxobutylidene)phosphoranes with α-Haloketones and α-Chloracetaldehyde
摘要:
3-Acyl-2-alkenylfurans were prepared by "Feist-Benary cyclocondensation" of (2,4-dioxobutylidene) phosphoranes with chloracetaldehyde and alpha-haloketones and subsequent Wittig reactions.
