An asymmetricsynthesis of (−)-N-acetylcolchinol is described based on a Suzuki–Miyaura coupling to generate the biaryl pharmacophore. The sole asymmetric centre was introduced by an asymmetric reduction of a dibenzosuberone derivative 24 using lithium borohydride in the presence of stoichiometric amounts of a chiral Lewisacid (TarB–NO2). A conjugate between an αVβ3 integrin-binding cyclic peptide
