✦ Synopsis

In the title compound, C 18 H 20 O 5 , the hydroxyl and dimethoxyphenyl substituents are in axial positions. The heterocyclic ring is in a half-chair conformation. The molecules are linked by OÐHÁ Á ÁO hydrogen bonds, leading to the formation of a chain extended throughout the whole of the crystal.

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
