(1R,1′R,3S,3′S)-5,5′,10,10′-Tetramethoxy-1,1′,3,3′-tetramethyl-3,3′,4,4′-tetrahydro-1H,1′H-8,8′-bi[benzo[g]isochromene]
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...
