说明

一般描述

3-Propyl-3-(2,3,5,6-tetrafluoro-4-nitrophenyl)-1,5-dioxaspiro[5.5]undecane-2,4-dione can be synthesized from pentafluoronitrobenzene, 3-propyl-1,5-dioxaspiro[5.5]undecane-2,4-dione, N,N-diisopropylethylamine and CH₃CN.

应用

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.
