Pd-catalyzed allylic C–H activation of simple olefins allows an easy entry to seven-membered N,O-heterocycles such as 1,4-benzoxazepines (1,4-BZOs), 1,4-benzodiazepinones (1,4-BZDs) and 1,4-oxazepanes in good to excellent yields. Straightforward derivatization of the olefinated 1,4-BZO shows the synthetic utility of this methodology.
Pd 催化的烯丙基 C-H 活化简单烯烃可以轻松进入七元N , O - 杂环,例如 1,4-苯并恶氮杂 (1,4-BZO)、1,4-苯并二氮杂 (1,4-BZD) ) 和 1,4-氧氮杂卓的产率。烯烃化 1,4-BZO 的直接衍生化显示了该方法的合成效用。
