A simple and efficient synthetic method for the one-pot synthesis of 1,3,4-thiadiazoles utilizing Vilsmeierreagent was developed. In this method carboxylic acids and hydrazine were converted to 1,3,4-thiadiazoles in the presence of Vilsmeierreagent and Lawesson's reagent. The influence of the thionation reagent, solvent, temperature and time, in this reaction was discussed. The developed methodology
This invention relates to a series of tricyclic compounds comprising a pteridinone core linked to a third heterocycloalkyl ring. The compounds are useful in the treatment of Hepatitis B viral infections. The invention also relates to pharmaceutical compositions comprising these compounds and methods of using the compounds in treatment.
Synthesis, characterization of novel isoindolinyl- and bis-isoindolinylphenylboronic anhydrides. Antiproliferative activity on glioblastoma cells and microglial cells assays of boron and isoindolines compounds
Boron compounds importance have been raising due to the development of its synthesis and remarkable biological activities, so in this manner the study here presented is focused on the synthesis of novel isoindolinylphenylboronic anhydrides (2a, 2c and 2e) and bis-isoindolinylphenylboronic anhydrides (2b and 2d), as well as a comparative study of the antiproliferative activity of these and their precursors
由于硼化合物的合成发展和出色的生物学活性,其重要性日益提高,因此,本文介绍的研究重点是新型异吲哚基苯基硼酸酐(2a,2c和2e)和双异吲哚基苯基硼酸酐(2b和2b )的合成。2d),以及它们及其前体(a - e),1(a - e)对胶质母细胞瘤细胞U373的抗增殖活性以及对正常小胶质细胞的细胞毒活性的比较研究。所有化合物均通过光谱法进行了表征。1个H,13 C,11 B NMR,IR和HRMS。在2b和2d的可变温度下的1 H和11 B NMR数据显示,由于分子内N→B配位和去配位键,在包含四面体和三角硼原子的物质之间达到平衡。B衍生物前沿分子轨道的研究表明2b'和2d'是比2a,2c和2e硬的分子,因此可以与第二个异吲哚啉反应获得2b和2d。而钾的HOMO位点衍生出1bK和1dK在NCHCO 2 K部分上,因此与2b '和2d'反应以获得2b和2d。这些结果阐明了与试剂的等分子比无关地获得2a
