✦ Synopsis

The title compound, C 34 H 56 O 5 , an oleanane triterpene, is a key intermediate in the synthetic route from betulin to 18(19)oleanene triterpenoids. In the molecule, all bond lengths and angles are normal. The hydroxy groups are involved in intermolecular O-HÁ Á ÁO hydrogen bonds, which link the molecules into zigzag chains running along the a axis. The crystal packing is further stabilized by weak intermolecular C-HÁ Á ÁO hydrogen bonds.
