说明

一般描述

N-Ethyl-N-isopropylpropan-2-aminium 4-oxo-3-(perfluoropyridin-4-yl)-1,5-dioxaspiro[5.5]undec-2-en-2-olate is a fluoroarylated-Meldrum′s acid adduct. It can be prepared by reacting pentafluoropyridine with cyclohexyl-Meldrum′s acid in the presence of N,N-diisopropylethylamine and acetonitrile.

应用

N-Ethyl-N-isopropylpropan-2-aminium 4-oxo-3-(perfluoropyridin-4-yl)-1,5-dioxaspiro[5.5]undec-2-en-2-olate may be used to synthesize ethyl 2-(2-(perfluoropyridin-4-yl)acetamido)-acetate and N-methoxy-N-methyl-2-(perfluoropyridin-4-yl)-acetamide.

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.
