The (4+2) cycloaddition of 1-ethoxy-2-fluoro-1,3- bis(trimethylsilyloxy)-1,3-diene with dimethyl acetylenedicarbox- ylate (DMAD) afforded dimethyl 4-fluoro-3,5-dihydroxyphthalate. Site-selectiveSuzuki-Miyaurareactions of its bis(triflate) provide a convenient approach to 3,5-diaryl-4-fluorophthalates.
