  Pd-Catalyzed C-3 functionalization of indolizines via C–H bond cleavage

  摘要：

  开发了新的过渡金属催化方法，通过直接断裂C-H键实现吲哚并环己烯的芳基化。一系列芳基三氟硼酸盐在Pd(OAc)2催化剂和AgOAc氧化剂的存在下与吲哚并环己烯反应，高效地得到芳基化的吲哚并环己烯。供电子和吸电子基团均表现良好，而溴和氯取代基也可耐受。此外，吲哚并环己烯在Pd催化反应中与3-苯基丙炔酸显示出相似的反应活性，从而获得相应的C-3炔基化吲哚并环己烯。这些方法使得吲哚并环己烯能够在一步中直接进行官能团化。

  efficiently prepared by direct C-3 arylation of indolizines using sodium arylsulfinates and arylsulfonyl hydrazides. Pd-catalyzed desulfitative C-3 arylation with sodium arylsulfinates was achieved with the assistance of peroxides, and the catalytic efficiency was promoted by N-containing ligands. Arylsulfonyl hydrazides were also successfully applied in Pd-catalyzed desulfitative C-3 arylation with indolizines

  通过使用芳基亚磺酸钠和芳基磺酰肼直接将吲哚嗪进行C-3芳基化，可以有效地制备衍生化的吲哚嗪。在过氧化物的辅助下，用芳基亚磺酸钠实现了钯催化的C-3芳族脱硫反应，并且通过含氮配体提高了催化效率。芳基磺酰肼也已成功地用于吲哚嗪类化合物在Pd催化的脱硫C-3芳基化中，在较温和的条件下，组分溶剂中的侧均偶联反应可得到抑制。两种方法均以高收率合成了各种衍生物，为合成C-3功能化的吲哚嗪分子提供了便利的方案。
• Regioselective Synthesis of 1‐Cyano‐3‐arylindolizines: Construction of Pyrroles via DDQ‐Mediated Ring Closure of Cyclopropyl Pyridines

  日期：2022.9.6

  A modular approach to a wide range of 1-cyano-3-(hetero)arylindolizines through aldol-cyclopropanation-oxidative cycloisomerization is described where DDQ was utilized for the regioselective synthesis of the pyrrole units from cyclopropyl pyridines for the first time. A key to success is regioselective oxidation of benzylic position by DDQ, which enabled us to access to one regioisomer out of two possible

  描述了一种通过醛醇-环丙烷化-氧化环异构化制备各种 1-氰基-3-(杂)芳基吲哚嗪的模块化方法，其中 DDQ 首次用于从环丙基吡啶中区域选择性合成吡咯单元。成功的关键是 DDQ 对苄基位置的区域选择性氧化，这使我们能够从两种可能的区域异构体中获得一种。在 DDQ 存在下，中氮茚 C2、C5 或 C7 位点的同源二聚化也首次被发现。

  An efficient strategy for the synthesis of indolizines from readily available starting materials via oxidative C-H functionalization and 5-endo-dig cyclization in one step has been demonstrated. This protocol represents wide substrate scope, high functional group tolerance, and selectivity. The structure of the product was confirmed by X-ray crystallographic studies. Ag2CO3 required of this tandem reaction can be recycled and reused after undergoing oxidative reaction. (C) 2014 Elsevier Ltd. All rights reserved.
• Pd-Catalyzed C-3 functionalization of indolizines via C–H bond cleavage

  New transition metal-catalyzed methods for the arylation of indolizines by the direct cleavage of C–H bonds have been developed. A wide range of aryltrifluoroborate salts react with indolizines in the presence of Pd(OAc)2 catalyst and AgOAc oxidant to give the arylated indolizines in high yields. Both electron-donating and electron-withdrawing groups perform smoothly while bromide and chlorine substituents are tolerated. In addition, the indolizines display similar reactivities in the Pd-catalyzed reaction with 3-phenylpropiolic acid to afford the corresponding C-3 alkynylated indolizines. These methods allow the direct functionalization of indolizines in one step.
