A stereoselective total synthesis of O,N-dimethylhamatine, an analogue of an axially chiral naphthylisoquinoline natural biarylproduct from tropical Ancistrocladus lianas, is reported. The route features a late-stage atropo-diastereoselective biaryl bond formation. Generation of this especially challenging, sterically hindered tetra-ortho-substituted array was achieved by using Nolan's (IPr*NHC)PdCinCl
