In the title compound, C 17 H 18 O 4 , the hydroxyl and methoxyphenyl substituents are in axial positions. The heterocyclic ring adopts a half-chair conformation. The molecules are linked by OÐHÁ Á ÁO hydrogen bonds, leading to dimerization.
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
