The first total synthesis of korupensamines A (1a) and B (1b), highly polar naphthylisoquinoline alkaloids and, simultaneously, 'monomeric building blocks' of the michellamines, is described. Key step is the Pd-II catalyzed intermolecular biaryl coupling of the two appropriately protected naphthalene and isoquinoline moieties (10) and (11), with the coupling positions activated by bromine and trialkylstannane substituents respectively.
