The first totalsynthesis of (−)‐euxanmodin B is described. An axiallychiral, enantiomerically pure biphenyl, available by enzymatic desymmetrization of σ‐symmetric biaryl diacetate, was used as the key chiral biaryl building block. Two annulation reactions allowed the construction of the xanthone–anthraquinone compositestructure with full stereochemical control.
