A range of novel 2-aryl-5-nitroquinolines have been synthesised as potential prodrug systems for bioreductive activation. Thus 5-nitroquinoline underwent vicarious nucleophilic substitution at C-6 with bromoform anion to give, after hydrolysis and reduction, the quinoline-6-methanol. Introduction of chlorine at C-2 was followed by palladium-catalysed Suzuki coupling to install the 2-aryl substituent
已经合成了一系列新颖的2-芳基-5-硝基喹啉,作为用于生物还原活化的潜在前药系统。因此5-硝基喹啉在C-6处用溴仿阴离子进行取代的亲核取代,在水解和还原后得到喹啉-6-甲醇。在C-2处引入氯,然后进行钯催化的Suzuki偶联,以安装2-芳基取代基。将荧光模型“药物” 7-羟基-4-甲基香豆素与6-羟基甲基偶联,并研究了其在硝基还原时的断裂情况。
