The title compound, C24H34O6S, (I), is an enantiopure sulfinyl adduct, prepared via stereocontrolled Diels-Alder cyclo­addition. The solid-state structure of (I) has been determined at room temperature by single-crystal X-ray diffraction. It is chemically similar to other cited structures; however, it presents a peculiar packing arrangement. Ab initio, density-functional theory (DFT) and semi-empirical (AM1, PM3 and PM5) full-geometry optimizations were carried out for (I). Calculated values of the structural parameters have been compared with those obtained by X-ray crystallography.

Experimental. Selected 1H NMR absorptions: δ 4.04 (dd, J2',3' = 6.5 and 4.6 Hz, H-2'), 3.81 and 3.79 (two s, 2 × OMe), 2.91 and 2.83 (AB system, J10'A,10'B = 13.2 Hz, H2–10'), 1.10 (s, H3–8'), 0.86 (s, H3–9'). Dimethyl (8aS,SS)-3,5,6,7,8,8a-hexahydro-4-[(1S)-isoborneol-10-sulfinyl]- 1,2-naphthalenedicarboxylate was eluted as a solid (m.p. 458–460 K, 48% yield). Selected 1H NMR absorptions: δ 4.12 (t, J2',3' = 5.6 Hz, H-2'), 3.80 and 3.78 (two s, 2 × OMe), 2.90 and 2.87 (AB system, J10'A,10'B = 13.2 Hz, H2–10'), 1.12 (s, H3–8'), 0.87 (s, H3–9'). Compound (I) was recrystallized from Et2O–petrol (2:1 v/v) (m.p. 473–475 K).

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.
