It has been shown that various combinations of nucleophilic aromatic substitution of hydrogen (SN H), SN ipso and the microwave-assisted Suzuki cross-coupling reactions are a versatile method for the synthesis of 5-(het)aryl-2-(thio)morpholinopyrimidine and 4,5-di(het)aryl-2-(thio)morpholinopyrimidine derivatives. All synthesized pyrimidines were found to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv.
研究表明,利用氢的亲核芳香取代反应(SN H)、SN ipso反应以及微波辅助的铃木交叉耦合反应的各种组合,是一种多功能的合成方法,可用于制备5-(杂)芳基-2-(硫)吗啉基嘧啶和4,5-二(杂)芳基-2-(硫)吗啉基嘧啶衍生物。所有合成的嘧啶在体外对结核杆菌H37Rv均表现出微摩尔浓度水平的活性。
