naphthylisoquinoline, pindikamine A (3), as a ‘skew’ analog of antiviral michellamines, is described. Because of the unusual coupling positions, this C2-symmetric quateraryl is the first michellamineanalog without axial chirality. Key steps of the total synthesis are the preparation of the molecular precursor 9 by intermolecular biaryl coupling, followed by a highly efficient oxidative ‘dimerization’

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.
