(6aS*,6bS*,11R*,11aR*)-6-(2-Furyl-methyl)-5,12-dioxo-5,6,6a,6b,7,11,11a,12-octa-hydro-furo[3',2':5,6]isoindolo[2,1-a]quinazoline-11-carb-oxy-lic acid.

The title compound, C(23)H(18)N(2)O(6), is the product of an intra-molecular thermal cyclo-addition within 1-malein-2-[(E)-2-(2-fur-yl)vin-yl]-4-oxo-3,4-dihydro-quinazoline. The mol-ecule comprises a previously unknown fused penta-cyclic system containing two five-membered rings (2-pyrrolidinone and furan) and three six-membered rings (benzene, 2,3-dihydro-4-pyrimidinone and dihydro-cyclo-hexa-ne). The central five-membered pyrrolidinone ring has the usual envelope conformation. The six-membered dihydro-pyrimidinone and dihydro-cyclo-hexane rings adopt a half-boat and a half-chair conformation, respectively. The dihedral angle between the planes of the terminal benzene and furan rings is 45.99 (7)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. Weak C-H⋯O hydrogen bonds consolidate further the crystal packing, which exhibits π-π inter-actions, with a short distance of 3.556 (3) Å between the centroids of benzene rings of neighbouring mol-ecules.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
