Abstract

The three-dimensional structure of the antibiotic oxolide, (9S,11S)-11-amino-9-deoxo-11,12-deoxy-9,12-epoxyerythromycin, was determined in CD2Cl2 through constrained molecular mechanics with constraints derived from proton NMR. The calculations yielded a well-defined global minimum. Data acquired for oxolide in D2O, although not as complete, indicate that the antibiotic adopts the same conformation in water.
