Microwave-accelerated fluorodenitrations and nitrodehalogenations: expeditious routes to labeled PET ligands and fluoropharmaceuticals
摘要:
Methods for the expeditious fluorination of arenes have been investigated, using readily available fluoride sources. An optimized procedure for microwave-accelerated fluorodenitration has been developed, giving good to excellent yields in less than 10 min, rendering it practical for use in the preparation of F-18 labeled ligands for PET imaging. Application of the method in the synthesis of CNS agents is demonstrated, and a practical method for the preparation of Substrates is also presented. (C) 2010 Elsevier Ltd. All rights reserved.
在此,我们报告了光激发硝基芳烃促进醇、胺、醛和亚胺厌氧氧化的方案。机理研究支持光激发硝基芳烃与醇和胺经历双氢原子转移(HAT)步骤以提供各自的酮和亚胺产物的观点。在醛和亚胺存在的情况下,连续发生 HAT 和氧原子转移 (OAT) 事件,分别产生羧酸和酰胺。这种转变适用于连续光流设置,从而缩短了反应时间。
signals in the part of the 6-azobpy ligand. The analysis of 1 H NMR spectra clearly identified the structure of the complex, in which the Ru 2+ ions are chelated by the bpy parts of the bridging 6-azobpy ligand. Electronic absorption and electrochemical properties are characterized by the presence of a low-lying π*level of the bridgingligand, manifested by a metal-to-ligand charge-transfer band extending
