In the title compound, C(34)H(38)O(6), the methyl groups on each pyran ring exhibit 1,3-cis stereochemistry, established during synthesis by pseudo-axial delivery of hydride during a lactol reduction step. In the crystal structure, the molecule lies on a twofold rotation axis and the torsion angle...

| description | In the title compound, C(34)H(38)O(6), the methyl groups on each pyran ring exhibit 1,3-cis stereochemistry, established during synthesis by pseudo-axial delivery of hydride during a lactol reduction step. In the crystal structure, the molecule lies on a twofold rotation axis and the torsion angle about the central diaryl bond is 41.3 (1)°. The molecules pack in a herringbone arrangement. |
