2,2,2-Trifluoroethanol is found to be a valuable synthetic tool proceeding to the chiral trifluoromethylated compounds via enantiotopic differentiating reaction and carbon-carbon bond formation with active fermenting baker’s yeast.

presence of perfluoroalkyl‐ or perfluoroaryl‐substituted silyl enol ethers smoothly provided the corresponding alkyl 2‐siloxycyclopropanecarboxylates in very good yields. The generated donoracceptor cyclopropanes are equivalents of γ‐oxo esters, which we demonstrated by their one‐pot transformations to yield fluorine‐containing heterocycles. A reductive procedure selectively afforded perfluoroalkyl‐substituted
