cross-coupling reaction of oxygen atom-substituted allylboronates with aryl/vinyl bromides, iodides, and triflates has been developed. The present coupling reactions proceeded smoothly to provide a variety of allylic siloxanes with high efficiency and excellent regioselectivity. This protocol features broad substrate scope, excellent functional group tolerance, and easy gram-scale preparation, and offers an
已经开发了氧原子取代的烯丙基硼酸酯与芳基/乙烯基溴化物、碘化物和三氟甲磺酸酯的高效钯催化 Suzuki-Miyaura 交叉偶联反应。本偶联反应顺利进行,提供了多种高效且区域选择性优异的烯丙基硅氧烷。该协议具有广泛的底物范围、出色的官能团耐受性和易于克级制备,并为烯丙醇及其衍生物的合成提供了一种替代方法。
