The recently reported capability of pentachloro-2-nitrobutadiene and some closely related derivatives to allow the synthesis of highly substituted acyclic as well as five-membered (hetero)cyclic compounds is herein extended to pyrimidines with an exceptional substitution pattern. Our novel approach starts from a 1,1-diamino-3,4,4-trichloro-2-nitrobuta-1,3-diene and an appropriate amidine. Some of the resulting perfunctionalized pyrimidines were subjected to further transformations to give promising candidates with respect to biological, especially pharmacological, activity.
最近报道的五氯-2-硝基丁二烯和一些密切相关的衍生物能够合成高度取代的无环和五元(杂)环化合物的能力在本文中扩展到具有特殊取代模式的嘧啶。我们的新方法从 1,1-二氨基-3,4,4-三氯-2-硝基丁-1,3-二烯和适当的脒开始。对所得的一些全功能化嘧啶进行进一步转化,以提供在生物活性、尤其是药理学活性方面有希望的候选物。
