Allgemeine Beschreibung

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.

Anwendung

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.

Organofluorine chemistry is an essential part of drug discovery programs as well as agrochemical programs and even plays a major role in materials chemistry. Despite the undeniable importance of fluorinated organic molecules, our ability to synthesize these substrates is lacking - though arguably it is better than that of Nature. Consequently, methods that allow facile access to fluorinated molecules are important especially when they provide unique access to fluorinated chemical space.
