This report describes a cascade reaction method for the synthesis of 2-arylpyrimidine derivatives via dehydrosulfurative carbon-carbon cross-coupling and concomitant oxidative dehydrogenation under a Pd/Cu catalytic system. It provides rapid and general access to a diverse range of 2-arylpyrimidines in a single step from a wide range of 3,4-dihydropyrimidin-1H-2-thiones (DHPMs) and arylboronic acids
该报告描述了在Pd / Cu催化体系下通过脱氢硫化碳-碳交叉偶联和伴随的氧化脱氢合成2-芳基嘧啶衍生物的级联反应方法。它可从一个范围广泛的3,4-二氢嘧啶-1 H -2-硫酮(DHPM)和芳基硼酸一步一步快速,通用地获得各种2-芳基嘧啶。
Structure-Based Designing, Solvent Less Synthesis of 1,2,3,4-Tetrahydropyrimidine-5-carboxylate Derivatives: A Combined In Vitro and In Silico Screening Approach
molecules possessing tetrahydropyrimidine derivatives have been synthesized having halogenated benzyl derivatives and carboxylate linkage. As previously reported, FDA approved halogenated pyrimidine derivatives prompted us to synthesize novel compounds in order to evaluate their biological potential. Methodology: Eight pyrimidine derivatives have been synthesized from ethyl acetoacetate, secondary amine

The present study is focused on the synthesis of DHPMs by using NiCoSe2 and NiCo2S4 as heterogeneous catalysts, and they are characterized by using XRD, SEM, TEM, BET and XPS. The NiCoSe2 and NiCo2S4 catalysts proved to be the most suitable catalytic system when compared to conventionally reported catalysts in terms of yield and reaction time. NiCoSe2 and NiCo2S4 are environment-friendly catalysts
本研究主要采用NiCoSE 2和NiCo 2 S 4作为多相催化剂合成DHPMs,并利用XRD、SEM、TEM、BET和XPS对其进行表征。与传统报道的催化剂相比,就产率和反应时间而言,NiCoSE 2和NiCo 2 S 4催化剂被证明是最合适的催化体系。 NiCoSE 2和NiCo 2 S 4是环境友好型催化剂,可循环使用5次以上,催化性能损失可忽略不计。因此,合成的催化剂成功地用于生物活性DHPM的合成,并且所有化合物均使用质谱和核磁共振波谱技术进行了表征。

Two series of 4-aryl-3,4-dihydropyrimidin-2(1H)-(thio) ones including monastrol (1a), have been synthesized by an environment-friendly methodology based on the combined use of citric acid or oxalic acid and TEOF (triethylorthoformate). The library was evaluated as inhibitor of cell proliferation on two glioma cell lines (human-U138-MG and Rat-C6). The compounds derived from thiourea 1f and 1d were more cytotoxic than monastrol. The compound derived from urea 2d showed the highest cytotoxic activity among the analyzed compounds.
