Methyl 7α,12α-Dihydroxy-3α-methacryloyloxy-5β-cholan-24-oate

The structure determination of the title compound, C₂₉H₄₆O₆, establishes the selective esterification of the hydroxyl group on position 3 of the steroid skeleton of the cholic acid methyl ester. The asymmetric unit contains one molecule and the crystal structure is stabilized by intermolecular hydrogen bonds. The two side chains on the steroid skeleton are quite flexible and each has two orientations; a disorder model was introduced and two sets of atoms were refined for the side chains.
