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
The title compound, C~20~H~17~NO~6~, was synthesized by the reaction of syringaldehyde with hippuric acid. The molecule adopts a __Z__ configuration about the central olefinic bond. The two benzene rings and the oxazolone ring are almost coplanar. The crystal structure is stabilized by weak intermol
