The syntheses of two cyclodeca[ij]isoquinoline derivatives, which embody the carbonframework of stephaoxocanidine, excentricine and the recently isolated stephalonganines A, B and C, are reported. The target tricyclic compounds were prepared from isovanillin, employing a ring-closing metathesis approach towards the synthesis of a benzocyclodecane-type common intermediate; different modifications of
