Natural macrocyclic bis(bibenzyls) exhibiting configurationally stable axially chiral biaryls are of high interest from a structural as well as from a synthetic point of view. An enantiopure sulfinyl auxiliary controlling an atropo-diastereoselective biaryl Suzuki coupling reaction has been investigated and promising results for the preparation of the biaryl moiety of cyclicbis(bibenzyls) like isoplagiochins
