We have developed an efficient and convenient strategy for the regioselective synthesis of new conformationally restricted butyrophenones of the quinoline series. The 7-aminomethyl-7,8-dihydro-6H-quinolin-5-ones 9 were obtained from protected alcohol 5 via the tosylate, and also in a one-pot reaction via bromo derivative 6, with moderate-to-good overall yields in both cases.
我们已经开发了一种高效,便捷的策略,用于喹啉系列新构象受限的丁苯酮的区域选择性合成。7-氨基甲基-7,8-二氢-6 H-喹啉-5-酮9通过甲苯磺酸酯从受保护的醇5中获得,并且也通过溴衍生物6在单锅反应中获得,总体中等至良好两种情况下的产量。
