Résumé

The title compound, C36H50O6S, forms an extended sheet of four fused rings which exhibit different conformations, as already observed in previously reported triterpene structures. There are weak intra- and intermolecular C-(HO)-O-... inter-actions. A weak C-Hc pi interaction also occurs, involving the tosyl group.
