yields by zinc in refluxing acetic acid. Under similar conditions, ethyl I'-anthracenoxyacetate (3i) with the ester group unaffected and 1,8-oxybis(ethyleneoxyethyleneoxy)anthracene (5) were also conveniently synthesized in 65 and 70% yields, respectively.
在回流乙酸中,锌可以将在不同位置la-h具有单、二和四醚基团的甲氧基-9,10-蒽醌直接还原为相应的甲氧基蒽3a-h,产率适中至良好。在类似条件下,酯基不受影响的 I'-蒽氧基乙酸乙酯 (3i) 和 1,8-氧基双(亚乙基氧基亚乙基氧基)蒽 (5) 也分别以 65% 和 70% 的产率方便地合成。
