  Synthesis of Some New Thiazole, Thiophene, and 2,3-Dihydro-1,3,4-thiadiazole and Pyrimidino[1,2-b]indazole Derivatives

  摘要：

  Hydrazonoyl halides 4a-g reacted with methyl carbodithioate 3 thioanilide 10 to give 1,3,4-thiadiazoles 5a-g and 13a-g, respectively. Thioanilide 10 reacted with omega-bromoacetophenones 14a-e to give the acyclic product 15a-e, which was converted to the thiophenes 16a-e and to the thiazoles 17a-e, respectively. Structures of the newly synthesized compounds were elucidated on the basis of elemental analysis, spectral data, and alternative synthesis route whenever possible.

  one-pot, regioselective and versatile procedure was developed for the synthesis of a series of highly functionalized pyrazole derivatives. The compounds were tested for antiproliferative activity on a panel of tumour and normal cells. 5-anilino-4-nitrile-3-phenyl pyrazoles emerged as the most promising derivatives, and compound 23 selectively inhibited the growth of estrogen-dependent SKMEL-28 and HeLa

  开发了一种一锅法、区域选择性和通用的方法来合成一系列高度官能化的吡唑衍生物。测试了这些化合物对一组肿瘤和正常细胞的抗增殖活性。5-苯胺-4-腈-3-苯基吡唑是最有希望的衍生物，化合物23选择性地抑制雌激素依赖性SKMEL-28和HeLa细胞的生长。对接模拟计算了 ERα- 23和 ERβ- 23复合物的微摩尔K i值，表明雌激素受体是这一系列吡唑的潜在生物学靶标。

  A novel, simple, and straightforward combinatorial method for the synthesis of new substituted 3-(arylamino)-6,7-dihydro-1H-indazol-4(5H)-one derivatives has been developed. The synthesis was achieved via a one-pot three-component reaction of aromatic isothiocyanates, substituted 1,3-cyclohexanediones, and hydrazine hydrate in dimethyl sulfoxide as a polar aprotic solvent. This methodology has the

• Spectroscopic, X-ray and DFT studies of prototropic tautomerism and photophysical properties of regioselectively designed new 3-, 2,3-substituted tetrahydro[4H]indazol-4-ones

  日期：2021.11

  prototropic tautomerism studies of 3-substituted-2H-indazol-4-ones have been described on the basis of spectral, LC-MS and DFT studies. The structural ambiguity was resolved by X-ray diffraction studies of compound 5 and validated by theoretical studies on the structure 5a and its regioisomer 6a. Photophysical studies (UV and fluorescence) of compounds 3 and 5 in different solvents are also reported

  二甲酮和异硫氰酸芳基酯在三乙胺中反应生成硫代酰胺2，其与肼或苯肼缩合生成 3-取代-2 H-吲唑3或 2,3-二取代-2 H-吲唑5，分别代替预期的区域异构体 3-取代的-1 H-吲唑4或 1,3-二取代的-1 H-吲唑6.光谱数据（IR、NMR 和质量）对结构区分几乎没有帮助。3-取代-2 H的质子互变异构研究-indazol-4-ones 已经在光谱、LC-MS 和 DFT 研究的基础上进行了描述。结构模糊性通过化合物5的 X 射线衍射研究解决，并通过对结构5a及其区域异构体6a 的理论研究进行验证。还报告了化合物3和5在不同溶剂中的光物理研究（紫外线和荧光）。
