Abstract
In the title compound, C15H22O4, the fully substituted benzene ring carries a methyl propanoate, two methoxy and three methyl substituents. Both methoxy substituents are almost orthogonal to the benzene ring plane. The methyl propanoate group is almost planar, r.m.s. deviation 0.0138 Å, and is inclined to the benzene ring plane by 80.26 (14)°. In the crystal, C—H...O hydrogen bonds form head-to-tail chains of molecules along theb-axis direction that are supported by very weak C—H...π(ring) contacts.
