| Popis: | The structure of the jatrophane diterpenoid (ES2), C46H56O15, has orthorhombic (P212121) symmetry. The absolute configuration in the crystal has been determined as 2R,3R,4S,5R,7S,8S,9S,13S,14S,15R [the Flack parameter is −0.06 (11)]. The molecular structure features intramolecular O—H...O and C—H...O hydrogen bonding. In the crystal, C—H...O hydrogen bonds link the molecules into supramolecular columns parallel to the a axis. One of the acetoxy substituents is disordered over two orientations in a 0.826 (8):0.174 (8) ratio. |
