The first totalsynthesis of a naphthylisoquinoline alkaloid is described. The required selective mixed coupling of the alkaloid moieties 2 and 6 is achieved -molecularly by the assistance of a reversibly thrown benzylether type auxiliary bridge.

The naphthyl isoquinoline alkaloid “triphyophylline” is structurally re-investigated. The constitution, as well as the relative configurations at C-1 and C-3, are confirmed as published previously. “Triphyophylline” is found to be a stable rotational isomer with respect to the biaryl linkage, the absolute configuration at the stereogenic axis is determined to be S.
