Descripción

General description

N-Ethyl-N-isopropylpropan-2-aminium 4-oxo-3-(2,3,5,6-tetrafluoro-4-(methoxycarbonyl)phenyl)-1,5-dioxaspiro[5.5]undec-2-en-2-olate is a fluoroarylated-Meldrum′s acid adduct. It can be prepared by reacting methyl-2,3,4,5,6-pentafluorobenzoate with cyclohexyl Meldrum′s acid.

Application

This compound undergoes cycloreversion to form the fluoro(hetero)aryl ketene, which undergoes efficient coupling with nucleophiles and allows rapid incorporation of highly fluorinated α-fluoro(hetero)aryl acetic acid derivatives.

Other Notes

Selective Perfluoro- and Polyfluoroarylation of Meldrum′s Acid
