A novel and efficient strategy for one-step synthesis of allylated quinolines and isoquinolines via palladium-catalyzed cyclization-allylation of azides and allyl methyl carbonate is developed for the first time. The results indicated that the regioselective synthesis of allyl- and diallyl-substituted quinolines/isoquinolines depends on different substituted groups at R(1) and R(4) positions, such
首次开发了一种新颖有效的策略,用于通过钯催化的叠氮化物和碳酸烯丙酯的环化-烯丙基化一步合成烯丙基化的喹啉和异喹啉。结果表明,烯丙基和二烯丙基取代的喹啉/异喹啉的区域选择性合成取决于R(1)和R(4)位置的不同取代基,例如H或其他基团。反应在100°C的DMF中在Pd(PPh3)4和K3PO4或NaOAc的存在下顺利进行,从而以高收率或高收率得到相应的烯丙基和二烯丙基取代的喹啉和异喹啉。
