RO5114436 is a chemokine receptor CCR5 antagonist that is a lead for the treatment of HIV and inflammatory disorders. The thirteen-step synthesis depicted features (1) a ruthenium-catalyzed asymmetric hydrogenation of an unprotected enamino ester using the (R)-MeOBIPHEP ligand and (2) a large-scale dipolar cycloaddition to generate the 3,7-diazabicyclo-[3.3.0]octane fragment H.
