Abstract Glycidyl esters and ethers undergo a regioselective andstereospecific opening of the oxirane ring upon treatment with trimethylsilyl halides (TMSX, X= Cl, Br, or I) in the presence of pyridine to produce the corresponding C2-O-trimethylsilyl-3 (1)-halo-sn- glycerols in high yields. Trifluoroacetylation across the trimethylsilyloxy system of such C3- synthons with trifluoroacetic anhydride (TFAA) in the presence of a halide anion (eg Bu 4 ...
