The mol-ecule comprises a fused hexa-cyclic system containing four five-membered rings (two dihydro-furan and two tetra-hydro-furan) in the usual envelope conformations and two six-membered rings (tetra-hydro-pyridinone and piperidine) adopting slightly flattened boat and chair conformations, respectively.
