The absolute con®guration of the title compound, C 38 H 44 O 8 , and in particular of its chiral cyclophane moiety, was determined by reference to the internal standard, (1S)camphanoate. Molecules are associated into columns parallel to the b axis by a series of CÐHÁ Á ÁO interactions.

The molecular structure of the title molecule with 50% probability displacement ellipsoids and the atomic numbering scheme.
In the title compound, C 16 H 14 O 3 , the furan ring makes an angle of 22.0 (1) with the plane of the four non-bridgehead C atoms of the six-membered ring. The molecules are linked by a short CÐHÁ Á ÁO interaction to form helical chains parallel to the b axis.
