[structure: see text]. Pactamycin, one of the most complex and densely functionalized aminocyclitol antibiotics known, presents synthetic challenges that include reactivity and sterics, relative and absolute stereochemistry, and functional group compatibility and protection. An approach is reported that features four different types of (cyclopentane) face selective functionalization reactions and results
