Gold(I)-catalyzed nucleophilic allylations of pyridinium and quinolinium ions with allylboronates are reported. Transmetalation of the allylboronate with gold produces nucleophilic allylgold(I) species that add to the 4-position of the azinium ion with complete regioselectivity to give functionalized 1,4-dihydropyridines and 1,4-dihydroquinolines. Density functional theory (DFT) calculations provided
报道了金(I)催化吡啶鎓和喹啉鎓离子与烯丙基硼酸盐的亲核烯丙基化。烯丙基硼酸酯与金的金属转移作用产生亲核烯丙基金 (I) 物质,该物质以完全区域选择性添加到吖嗪离子的 4 位上,得到官能化的 1,4-二氢吡啶和 1,4-二氢喹啉。密度泛函理论 (DFT) 计算提供了机理见解。
