Abstract
AbstractThe structural puzzle of amipurimycin, a peptidyl nucleoside antibiotic, is solved by total synthesis and X‐ray diffraction analysis, with the originally proposed configurations at C3′ and C8′ inverted and those at C6′, C2′′, and C3′′ corrected. A similar structural revision of the relevant miharamycins is proposed via chemical transformations and then validated by X‐ray diffraction analysis. The miharamycins bear an unusual trans‐fused dioxabicyclo[4.3.0]nonane sugar scaffold, which was previously assigned as being in the cis configuration.
