- Structure of the Novel Antibiotics Boxazomycins A, B, and C
-
Structures of three new antibiotics, boxazomycins A, B, and C, were determined on the basis of their spectral properties, including modern NMR techniques such as INADEQUATE and NH-COLOC spectra.Observation of long-range couplings between phosphorus and carbon atoms of a phosphate derivative of boxazomycin A was helpful for the structure elucidation.Boxazomycins have a novel 7-methyl-2-(2-methylpyrimidin-4-yl)benzoxazole-4-carboxylic acid skeleton.
