A synthesis of 6-deoxyerythronolide B is reported that uses a late-stage C–H oxidative macrocyclization reaction to forge the key macrocyclic core found in the erythromycins. By installing oxygen at a late-stage, this strategy improves synthetic efficiency by minimizing the ‘oxygen load’, and provides stereochemical versatility at the site of oxidation.
