environments which transform organic matter. Some zygomycetes of gender Mucor have attracted interest in health sector. Due to its ability as opportunistic microorganisms infecting immuno-compromised people and to the few available pharmacological treatments, the mucormycosis is receiving worldwide attention. Concerning to the pharmacological treatments, some triazole-based compounds such as fluconazole

scope of >30 examples under modest reaction conditions. A variety of 2-aminobenzyl alcohols containing electron-donating and electron-deficient groups and (2-aminopyridin-3-yl)methanol are converted to the corresponding quinolines and naphthyridines using ambient air as an oxidant in the presence of KOH. We synthesized a wide range of derivatives, including some of the bioactive antimalarial drug chloroquine
producing quinoline, pyrrole, and pyridine derivatives through acceptor-less dehydrogenative coupling (ADC) procedures at 90–110 °C under neat/solvent-free conditions and achieved good to exceptional yields of those nitrogen-containing heterocycles. This methodology is attractive because it is environmentally benign and allows for the “green” synthesis of nitrogen-containing heterocycles. All that is required
创建了由吡啶甲酰胺基部分结合在一起的三重 Ir( III ) 配合物。在我们早期的研究中,我们证明了在催化量的 Cp*Ir( III ) 催化剂和t BuOK 存在下,在甲苯中由酮或仲醇与伯醇生产 α-烷基化酮的配合物的催化活性使用借氢技术在 110 °C 下进行。早期许多研究小组以2-氨基醇和酮或仲醇衍生物为起始原料合成了喹啉、吡咯和吡啶衍生物,但这些情况下的反应条件并不适合绿色合成,如催化剂负载量较多、碱含量较高等。负荷大、反应时间长、温度高。此外,大多数反应都含有磷化氢(一种危险的副产品)以及催化剂。考虑到这些缺点,我们在前期工作取得优异成果后尝试扩大催化剂的用途,并通过无受体脱氢偶联(ADC)程序在90℃下成功生产了喹啉、吡咯和吡啶衍生物。在纯净/无溶剂条件下 –110 °C,这些含氮杂环化合物的产率达到了良好甚至异常的收率。这种方法很有吸引力,因为它对环境无害,并且可以“绿色”合

A new and efficient strategy for the synthesis of substituted quinolines viaelectrophilic cyclization is developed. The intramolecular cyclization of 1-azido-2-(2-propynyl)benzene 1 proceeds smoothly in the presence of electrophilic reagents (I2, Br2, ICl, NBS, NIS, and HNTf2) in CH3NO2 at room temperature or in the presence of catalytic amounts of AuCl3/AgNTf2 in THF at 100 °C to afford the corresponding
Regiodivergent C–H bond arylation of fluorinated 2-arylpyridines and 2-arylquinolines has been developed. The use of Pd catalyst allows functionalization of the C–H bond of the aryl flanked by two fluorine atoms (most acidic position), while using Ru catalyst, the arylation takes place on the aryl unit at the ortho position of the heterocycle. Both reaction conditions exhibit a good functional group
