    Efficient synthesis of various 2‐oxo(thioxo)‐1,2,3,4‐tetrahydropyrimidines containing acetyl, carboethoxy, carbomethoxy and carboxamide groups on 5‐position of the N1‐substituted and N1‐unsubstituted heterocyclic ring was achieved using cobalt hydrogen sulfate Co(HSO4)2 under thermal conditions.

    Excessive UV-B exposure is well known to be a risk factor for corneal phototoxicity including direct DNA damage and disturbances in the antioxidant balance. Here, we showed a successful synthesis of a water-soluble and biocompatible small molecule DHPM 1 with dihydropyrimidinthione skeleton, which could effectively protect human corneal epithelial (HCE-2) cells from UV-B damage. In separate experiments, DHPM 1 absorbed UV-B rays and exhibited scavenging activity against intracellular ROS induced by UV-B radiation, thereby reducing the levels of DNA fragmentation. Additionally, UV-B exposure increased the expression of cleaved caspase-3, as well as the ratio of Bax/Bcl-2 at protein levels, while pretreatment with DHPM 1 significantly reversed these changes. To the best of our knowledge, this is the first report of a study based on dihydropyrimidinthione derivatives to develop a promising eye drops, which may well find extensive applications in UV-B caused corneal damage.

    agents and a1aantagonists. Since the first straightforward synthetic method for DHPMs was reported by Biginelli in 1893, many improved protocols were developed. Not only new catalysts and reaction conditions were explored but also some novel reactive species were formed. The scope of the Biginelli reaction extended to various building blocks, so a large number of multifunctional pyrimidine derivatives with
    由于杂环上的六个功能点,二氢嘧啶酮 (DHPM) 具有广泛的合成重要性。DHPMs 还具有多种生物和药物活性,如钙通道阻滞剂、抗高血压剂和 a1a 拮抗剂。自从 1893 年 Biginelli 报告了第一个直接的 DHPM 合成方法以来,开发了许多改进的协议。不仅探索了新的催化剂和反应条件,而且形成了一些新的反应物种。Biginelli 反应的范围扩展到各种构建模块,因此获得了大量具有重要生物学特性的多功能嘧啶衍生物。其中,N1 取代的 DHPMs 也具有重要的生物活性和区域选择性。然而,关于 DHPM 的 N1-烷基化的参考文献很少,而且它们在产率、有毒试剂和反应条件方面都有局限性。尿素上的取代基主要限于 Me 和 Et。这鼓励我们开发一种新颖有效的方法来合成更多 N1 取代的 DHPM。作为耐水路易斯酸催化剂,金属磺酸盐被认为在合成化学中具有广泛的应用前景。它们高效、无毒并可重复使用。作为我们在金属磺酸盐催化的
