Compound 7:

Figure S5. Truncated 1H NMR spectrum of hydrocarbon 7 (500 MHz, CDCl3) (mixture of diastereomers). The major isomer gives rise to two AB patterns at 3.54 and 3.12 (4 H) and 3.31 and 3.12 (4 H) due to two sets of equivalent methylene groups, the singlet at 3.72 for 9-H and 9’-H as well as the doublet at 6.40 (2 H) and the triplet at 6.82 (2 H) which indicates the magnetic shielding of the rims of two equivalent benzene rings. Some resonances of the minor diastereomer are indicated by the lettering in italics.
Figure S6A.Two stable conformations of the (9S,9’S)-diastereomer of hydrocarbon 7, calculated by molecular modeling (AM1, HyperChem). Left column: most stable form with gauche orientationof 9-H and 9’-H; right column: by3.3 kcal mol1 less stable form with nearly antiperiplanar orientation of 9-H and 9’-H; (a) and (b) views along the C9-C9’ bond, (c) and (d) side views, (e) and (f) back views showing the cis-stilbene moieties.
Figure S6B.Most stable conformation of the (9R,9’S)-diastereomer of hydrocarbon 7, calculated by molecular modeling (AM1, HyperChem). According to the calculations, this diastereomer is 2.9 kcal mol1 less stable than the (9S,9’S)-diastereomer. (a) frontside view onto the four methlene groups and (b) backside view.
