Computational methods and high-field NMR experiments on the epothilone pharmacophore have enabled us to distinguish epoxide/olefinic conformer I and epoxide/olefinic conformer II and, subsequently, to determine which most accurately describes the bioactive conformation for this region. cache/qz20sq89r9h.txt txt/qz20sq89r9h.txt
