| Popis: | The asymmetric unit of the title compound, C58H96N2O4, contains two crystallographically independent molecules. All cyclohexane rings are in chair conformations, while the furan ring is in an envelope conformation in one molecule and a twist conformation in the other. Two acetaldehyde and one isobutane groups are disordered over two orientations with refined site occupancies of 0.940 (4):0.060 (4) and 0.791 (7):0.209 (7), respectively. In the crystal, molecules are stacked along the a axis through van der Waals interactions. |
