Abstract A series of novel N -(3-furan-2-yl-1-phenyl-1 H -pyrazol-5-yl) amides derivatives were designed and synthesized. Their structures were confirmed by 1 H NMR, 13 C NMR and HRMS. All title compounds were evaluated for their herbicidal and antifungal activities. Preliminary bioassay results indicated that the title compounds showed good to moderate herbicidal activity at 1000 mg/L. Compound 6q
摘要设计合成了一系列新颖的N-(3-呋喃-2-基-1-苯基-1 H-吡唑-5-基)酰胺衍生物。它们的结构通过1 H NMR,13 C NMR和HRMS确认。评价所有标题化合物的除草和抗真菌活性。初步的生物测定结果表明,标题化合物在1000 mg / L时表现出良好至中度的除草活性。化合物6q表现出对Digitaria sanguinalis(L)Scop。,Amaranthus retroflexus L.和Arabidopsis thaliana的最佳活性,抑制程度为5。化合物6d对D. sanguinalis的抑制程度为5级。此外,在50 mg / L时,大多数化合物对菌核菌都表现出良好的体外抗真菌活性,而化合物6c对沙门氏菌和sasakii菌则表现出超过90%的抗真菌活性。
Microwave synthesis of 1-aryl-1H-pyrazole-5-amines
A microwave-mediated synthesis of 1H-pyrazole-5-amines utilizing 1 M HCl at 150 °C was developed in order to provide products in a matter of minutes with minimal purification. Most reactions are complete in only 10 min and can be isolated via a simple filtration without the need for further purification by column chromatography or recrystallization. This method tolerates a range of functional groups
为了在几分钟内以最少的纯化提供产物,开发了利用1 M HCl在150°C的微波介导的1 H-吡唑5-胺的合成方法。大多数反应仅在10分钟内即可完成,可以通过简单的过滤进行分离,而无需通过柱色谱法或重结晶法进一步纯化。该方法可耐受一定范围的官能团,并且可以以毫克至克为单位进行测量。
Highly functionalized benzodiazepine skeletons were efficiently synthesized via a Rh(iii)-catalyzed selective mono- and dual-C–H bond functionalization/cyclization reaction between readily available 1-aryl-5-aminopyrazoles and iodonium ylides under.

The novel series of furan-bearing pyrazolo[3,4-b]pyridines were designed as cyclin-dependent kinase 2 (CDK2) inhibitors and as p53–murine double minute 2 (MDM2) inhibitors. The newly synthesized compounds were screened for their antiproliferative activity toward hepatocellular carcinoma (HepG2) and breast cancer (MCF7) cell lines. The most active compounds on both cell lines were additionally evaluated
