via catalytic hydrogenation of the corresponding acetamido-substituted quinolines and isoquinolines followed by acetamide hydrolysis is described. The yields of the products are good when the acetamido substituent is present on the pyridine ring and moderate with the acetamido substituent on the benzene ring. This method has also been applied to the regioselective reduction of quinoline substrates bearing
描述了一种通过相应的乙酰胺基取代的喹啉和异喹啉的催化氢化,然后乙酰胺水解制备氨基取代的5,6,7,8-四氢喹啉和5,6,7,8-四氢异喹啉的方法。当乙酰氨基取代基存在于吡啶环上且与乙酰氨基取代基在苯环上适度结合时,产物的收率良好。此方法也已应用于带有其他取代基(R = OMe,CO(2)Me,Ph)的喹啉底物的区域选择性还原。
