A novel trifluoromethyl ketene silyl acetal (4) of methyl trifluoropyruvate (1) was prepared in 82% yield by metal Mg reduction in a (TMS)Cl/THF system. Subsequent carbon−carbon bond formation such as Mukaiyama aldol, Michael addition, and other nucleophilic reactions of 4 at the trifluoromethylated carbon with various electrophiles gave various coupling products in high yields.
