芳氧基和氨基取代的E-和Z-乙基-3-丙烯酸酯的立体定向合成因其在聚合物工业和药物化学中的潜力而受到关注。在铜催化 ( E )- 和 ( Z )-3-碘代丙烯酸乙酯与苯酚和N-杂环的交叉偶联反应过程中,我们发现了一种非常简单的(非金属)方法用于芳氧基和氨基取代的立体定向合成丙烯酸酯。为了研究芳氧基和氨基取代的丙烯酸酯的立体选择性这个长期存在的问题,一系列O-和N-取代的亲核试剂被允许与( E )-和( Z )-3-碘代丙烯酸乙酯反应。不同碱的筛选表明,DABCO(1,4-二氮杂双环[2.2.2]辛烷)以立体有择方式成功地将( E )-和( Z )-3-碘代丙烯酸乙酯转化为芳氧基和氨基取代的丙烯酸乙酯。本文详细介绍了这种 DABCO 介导的芳氧基和氨基取代的E-或Z-丙烯酸酯的立体定向合成。

Novel acrylic acid ethyl ester derivatives were synthesized and evaluated as potentialagents against Mycobacterium species. A versatile and efficient copper-catalyzed coupling process was developed and used to prepare a library of substituted acrylic acid ethyl ester analogs. Minimum inhibitory concentration assays indicated that two of these compounds 3 and 4 have greater in vitro activity against
