일반 설명

4-(2,4-Dioxo-3-propyl-1,5-dioxaspiro[5.5]-undecan-3-yl)-2,3,5,6-tetrafluorobenzonitrile is a substituted Meldrum′s acid derivative. It can be prepared by reacting pentafluorobenzonitrile with 3-propyl-1,5-dioxaspiro[5.5]-undecane-2,4-dione.

애플리케이션

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.

Selective perfluoro- and polyfluoroarylation of Meldrum's acid.

Sameera M Senaweera et al.

The Journal of organic chemistry, 79(21), 10466-10476 (2014-10-02)

This work describes the facile and mono-selective per- and polyfluoroarylation of Meldrum's acid to generate a versatile synthon for highly fluorinated α-phenyl acetic acid derivatives, which provide straightforward access to fluorinated building blocks. The reaction takes place quickly, and most
