Addition of molecular fluorine to cis-2-cyclopentene-1,4-diol gave the
cis-anti adduct stereoselectively. This meso diol was dissymmetrized
by means of acetylation under lipase catalysis to afford the monoaceta
te with a high enatiomeric purity. Oxidation of the monoacetate follow
ed by elimination of hydrogen fluoride under basic conditions furnishe
d the titled compound which is an attractive building block for chiral
fluorinated molecules.
