The title compound, C(18)H(20)O(4), was prepared in high yield from 3,5-dimethoxy-styrene via a Ru-catalysed homo-olefin metathesis. Exclusive formation of the E-configurated isomer was observed. Inter-estingly, one symmetric unit contains two mol-ecules adopting an s-syn-anti and and an all-s-anti conformation.
