  Synthesis and Anticancer Activity of 2-Aryl-3-methylbenzofuro[3,2-b]pyrazolo[4,3-e]azepine-4,11(2H,10H)-dione and 2-Aryl-3,7,9-trimethylpyrido[3',2':4,5]thieno[3,2-b]pyrazolo[4,3-e]azepine-4,11(2H,10H)-diones

  摘要：

  The reactions of ethyl 1-aryl-4-(2-bromoacetyl)-5-methyl-1H-pyrazolocarboxylates withortho-hydroxybenzonitrile and 4,6-dimethyl-2-thioxo-1,2-dihydropyridine-3-carbonitrile gave previously unknown 2-aryl-3-methylbenzofuro[3,2-b]pyrazolo[4,3-e]azepine-4,11(2H,10H)-diones and 2-aryl-3,7,9-trimethylpyrido[3',2':4,5]thieno[3,2-b]pyrazolo[4,3-e]azepine-4,11(2H,10H)-diones, respectively. It was found that this reaction occurred as a tandem process. The synthesized compounds were sceened for anticancer activity and exhibited moderate activity against the most part of malignant cancer cells.

• In Situ Generation of Nitrilimines from Aryldiazonium Salts and Diazo Esters: Synthesis of Fully Substituted Pyrazoles under Room Temperature
  作者：Ying Shao、Hao Zheng、Junfeng Qian、Xiaobing Wan

  日期：2018.4.20

  A novel one-pot synthesis for fully substituted pyrazoles has been well developed via the in situ generation of nitrilimines from aryldiazonium salts and diazo esters and a subsequent cycloaddition with 1,3-dicarbonyl compounds. High yields, mild conditions, wide substrate scope, and operational simplicity are the significant advantages of this methodology.

  通过从芳基重氮盐和重氮酯原位生成腈亚胺以及随后与1,3-二羰基化合物进行环加成反应，已开发出一种完全取代的吡唑的新型一锅合成方法。高产率，温和的条件，广泛的底物范围和操作简便性是该方法的显着优势。

  Reactions of arenediazonium chlorides with ethyl 2-methyl-and 2-chloro-4-oxobutanoates gave, respectively, ethyl 2-(arylhydrazono)propanoates and chloro(arylhydrazono)acetates. Ethyl 2-(arylhydrazono)-propanoates reacted with the Vilsmeier-Haak reagent to give ethyl 1-aryl-4-formyl-1H-pyrazole-3-carboxylates. Ethyl 1-aryl-4-acetyl-5-methyl-1H-pyrazole-3-carboxylates were obtained by reaction of chloro(arylhydrazono) acetates with acetylacetone. Reactions of the obtained pyrazole derivatives with hydrazine and methylhydrazine led to the formation of the corresponding 3,4-R(2)(1)-6-R(2)-2-aryl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-ones (R(1), R(2) = H, Me) which were subjected to alkylation and sulfurization.

  Ethyl 1-aryl-4-acetyl-5-methyl-1H-pyrazole-3-carboxylates reacted with phenylhydrazine to give the corresponding hydrazones, ethyl 1-aryl-5-methyl-4-[1-(phenylhydrazinylidene)ethyl]-1H-pyrazole-3-carboxylates, which were converted to ethyl 1'-aryl-4-formyl-5'-methyl-1-phenyl-1H,1'H-3,4'-bipyrazole-3'-carboxylates by treatment with the Vilsmeier-Haack reagent. No indole derivatives were formed from the same hydrazones under the Fischer reaction conditions, but cyclization to 2-aryl-3,4-dimethyl-6-phenyl-2,6-dihydro-7H- pyrazolo[3,4-d] pyridazin-7-ones was observed.

  日期：2010.10

  Bromination of ethyl 1-aryl-4-acetyl-5-methyl-1H-pyrazole-3-carboxylates gave ethyl 1-aryl-4-(bromoacetyl)-5-methyl-1H-pyrazol-3-carboxylates which were used to alkylate benzenethiol and heterocyclic thiones at the sulfur atom. Reactions of the resulting S-alkylation products with hydrazine or methylhydrazine involved closure of pyridazine ring to afford 2-aryl-3-methyl-4-[phenyl(or hetaryl)sulfanylmethyl]-6,7-dihydro-2H-pyrazolo[3,4-d]pyridazin-7-ones.
