2,2-Dimethyl-5-(2,3,4-trimethoxybenzylidene)-1,3-dioxane-4,6-dione

Abstract

The title compound, C16H18O7, was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 2,3,4-trimethoxybenzaldehyde. The 1,3-dioxane ring is in a slightly distorted boat conformation. The crystal structure is stabilized by weak intermolecular C—H...O hydrogen bonds.
