General description

3-Propyl-3-(2,3,5,6-tetrafluoro-4-(trifluoromethyl)phenyl)-1,5-dioxaspiro[5.5]undecane-2,4-dione is a perfluorinated organic building block. It can be prepared by reacting octafluorotoluene, 3-propyl-1,5-dioxaspiro[5.5]-undecane-2,4-dione, N,N-diisopropylethylamine and CH3CN.

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.

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.

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
