Abstract

Abstract Methoxy-9, 10-anthraquinones with mono-, di-and tetraether groups at different positions 1a-h can be directly reduced to the corresponding methoxyanthracenes 3a-h in moderate to good yields by zinc in refluxing acetic acid. Under similar conditions, ethyl 1′- anthracenoxyacetate (3i) with the ester group unaffected and 1, 8-oxybis ( ethyleneoxyethyleneoxy) anthracene (5) were also conveniently synthesized in 65 and 70 ...
