  Pd^II-Catalyzed Di-o-olefination of Carbazoles Directed by the Protecting N-(2-Pyridyl)sulfonyl Group

  摘要：

  Despite the significance of carbazole in pharmacy and material science, examples of the direct C-H functionalization of this privileged unit are quite rare. The N-(2-pyridyl)sulfonyl group enables the Pd-II-catalyzed ortho-olefination of carbazoles and related systems, acting as both a directing and readily removable protecting group. This method features ample structural versatility, affording typically the double ortho-olefination products (at Cl and C8) in satisfactory yields and complete regiocontrol. The application of this procedure to related heterocyclic systems, such as indoline, is also described.

  Synthesis of Indolines via Pd(II)-Catalyzed Amination of C–H Bonds Using PhI(OAc)₂ as the Bystanding Oxidant

  摘要：

  The Pd(II)-catalyzed intramolecular C-H amination of 2-pyridinesulfonyl-protected phenethylamine derivatives has been achieved using Phl(OAc)(2) as a bystanding oxidant, providing access to a variety of substituted indoline derivatives in good yields. The use of the 2-pyridlnesulfonyl protecting group allows for facile deprotection following C-H functionalization.

  A general and efficient method for the intermolecular direct C-7-selective C–H alkenylation of indolines using palladium(II) as the catalyst and molecular oxygen as the sole oxidant has been developed. The reaction showed complete regio- and stereoselectivity. All products were E-isomers at the C-7 position, and no Z-isomers or other position substituted products could be detected. The approach also

  已经开发了一种通用有效的方法，以钯（II）为催化剂，分子氧为唯一氧化剂，使吲哚的分子间直接C-7-选择性CH链烯基化。反应显示出完全的区域选择性和立体选择性。所有产物在C-7位均为E-异构体，未检测到Z-异构体或其他位置取代的产物。该方法还提供了合成C-7烯基化吲哚的有效途径。
