Abstract

Four model compounds having syn and anti 1,3-diol type moieties corresponding to C-8/C-10 and C-14/C-16 positions contained in the C-4Å`C-17 fragment of theonezolides A-C were prepared. Comparison of their spectral data suggested that the 1,3-diol at C-8/C-10 and the OH/OMe groups at C-14/C-16 positions of theonezolides A-C were both syn.
