(S)-4,16-dihydroxymethyl-[2.2]para-cyclophane bis-(1S)-camphanoate

The absolute configuration of the title compound, C38H44O8, 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 C-H...O interactions.
