In the crystals of the title compound, C 19 H 24 O 8 , the molecules adopt a conformation in which the bulky 2,6-dimethoxyphenoxy and 4-hydroxy-3,5-dimethoxyphenyl groups are distant from each other. The O(phenoxy)ÐCÐCÐC(phenyl) torsion angle between these groups is À177.27 (10) . The conformation i

The title compound, C 26 H 30 O 7 , was obtained by the Grignard reaction of one molecule of 4-methoxybenzylmagnesium chloride with two molecules of 3,5-dimethoxybenzaldehyde. The two new chiral centers have the same absolute con®guration R (S), and the two hydroxyl groups, surrounded by the three b
