  缺电子的4-和6-取代的靛红的区域特异性合成的改进程序

  摘要：

  对于各种底物，已经研究了由卤代硝基苯1a-g分四步合成4和6取代的isatins 5a-g的区域特异性合成（方案1）。该程序利用易于获得，易于处理的材料，并且在大多数情况下，不需要纯化中间体或最终产物。伊斯兰素的收率在26％至75％之间（表1）。据报道，已知的靛红的产率提高了，并且以前没有报道过的靛红的合成也得到了报道。该方法与已知方法一起提供了合成的完整的靛红区域异构体。

  Synthesis and Antiviral Evaluation of Trisubstituted Indole N-Nucleosides as Analogues of 2,5,6-Trichloro-1-(β-d-ribofuranosyl)benzimidazole (TCRB)

  摘要：

  2,5,6-Trichloro-1-(beta-D-ribofuranosyl)benzimidazole (TCRB) and 2-bromo-5,6-dichloro-1-(beta-D-ribofuranosyl)benzimidazole (BDCRB) are nucleosides that exhibit strong and selective activity against human cytomegalovirus (HCMV). Selected polyhalogenated indole nucleosides have now been synthesized as 3-deaza analogues of the benzimidazole nucleosides using the sodium salt glycosylation method. 2-Benzylthio-1-[2-deoxy-3,5-bis-O-(4-methylbenzoyl)-beta-D-erythropentofuranosyl]-5,6-dichloroindole (8) was prepared stereoselectively via the coupling of a 2-deoxyribofuranosyl alpha-chloride derivative with the sodium salt of 2-benzylthio-5,6-dichloroindole (5). Compound 8 was then elaborated into the targeted 2-benzylthio-1-(beta-D-ribofuranosyl)-5,6-dichloroindole (18) in five steps. 2,5,6-Trichloro-(1-beta-D-ribofuranosyl)indole (19) was prepared using the same synthetic route with 2,5,6-trichloroindole (6) as the starting material. We were subsequently able to prepare 19 in three steps using a modification of the sodium salt glycosylation method. 2-Bromo-5,6-dichloro-1-(beta-D-ribofuranosyl)indole (25) was also prepared using the same procedures. Target compounds were tested for activity against HCMV, herpes simplex virus type 1 (HSV-1), and human herpes virus six (HHV-6) and for cytotoxicity. All of the compounds were less active against HCMV than TCRB and weakly active or inactive against HSV-1 and HHV-6.

• A Mild and Direct C(sp₃)–S Cross-Coupling of Oxindoles with Thiols: Synthesis of Unsymmetrical 3-Thiooxindoles

  Herein, an operationally simple and mild strategy to construct sulfenation of oxindoles with a series of thiols in the absence of transition metals was developed. This methodology provides an efficient way to directly form a C-S bond at the C-3 position of oxindoles under mild reaction conditions with a cheap and common solvent and base in moderate to good yields.

• Synthesis of Oxindoles via SmI2-Promoted Reduction of 2-Nitrophenylacetic Acids
  作者：Songlin Zhang、Pengkai Wang

  DOI：10.1055/a-2175-1008

  日期：2024.1

  reduction of 2-nitrophenylacetic acids to oxindoles promoted by SmI2 is reported for the first time. This reaction involving the reduction of nitro group proceeds through N–O bond cleavage and direct condensation with the neighboring carboxyl group. From a synthetic point of view, a new method for the synthesis of oxindoles in mild neutral conditions is developed.
