The catalyst-free allylation of isatins with allyltrichlorosilane was performed smoothly in DMF under mild conditions and moderate to excellent yields (60%-94%) were obtained. This protocol provided a new and efficient approach for the preparation of 3-allyl-3-hydroxy-2-oxindoles.
在温和条件下,使用无催化剂的 allyltrichlorosilane 对异
吲哚进行亲烯基化反应,顺利地在
DMF 中进行,获得了中等到优异的产率(60%-94%)。这一方法提供了一种制备 3-烯基-3-羟基-2-氧
吲哚的新颖高效途径。
