The synthetic pathway leading to 4-H-furo[3,2-f]pyrrolo[1,2-a][1,4]diazepines is described in five steps starting from 2-hydroxyketones via 2-amino-3-furonitriles. 相似文献
A new efficient pathway to synthesise 6-(het)aryl-2-methyl-2,3-dihydro-1H-pyridin-4-ones is described. This reaction sequence involved, as a key step, a Suzuki cross-coupling reaction between various boronic acids and an 6-iodo-2,3-dihydropyridin-4-one. A final deprotecting step furnished the attempted products. 相似文献
Mesoporous iron phosphate containing CTAB as templating agent was synthesized and characterized by means of X-ray diffraction, Fourier transform infrared spectroscopy and TGA techniques. The mesoporous material shows a highly ordered structure, that collapses when submitted to extraction with acetate ions. The treatment of the exchanged samples at 573 K under nitrogen atmosphere leads to amorphous phases with an electrochemical behaviour typical of carbon-coated iron phosphate electrodes. The existence of this coating, proceeding from incomplete pyrolysis of the organic exchange agent, enhances the electronic properties of the system, as evidenced by galvanostatic experiments and impedance spectroscopy measurements. 相似文献
A LabVIEW®-based software for the control of the fully automated multi-sequential flow injection analysis Lab-on-Valve (MSFIA-LOV) platform AutoRAD performing radiochemical analysis is described. The analytical platform interfaces an Arduino®-based device triggering multiple detectors providing a flexible and fit for purpose choice of detection systems. The different analytical devices are interfaced to the PC running LabVIEW®VI software using USB and RS232 interfaces, both for sending commands and receiving confirmation or error responses. The AUTORAD platform has been successfully applied for the chemical separation and determination of Sr, an important fission product pertinent to nuclear waste.
A one-pot synthesis of novel poly-substituted phenanthrenes is described in this article through a Suzuki-Miyaura cross-coupling followed by a Dieckmann-Thorpe ring closure under microwave irradiation. The selection of the appropriate starting materials allowed us to introduce diversity on various positions of the phenanthrene ring system. 相似文献
