  3-Arylindolizines were prepared by one-pot domino reactions from benzyl halides with pyridine (or isoquinoline) and cyclic or acyclic dihalide-substituted electron-deficient alkenes in the presence of potassium carbonate via in situ generated N-ylide intermediate. Both electron-donating and electron-withdrawing groups are tolerated in the aryl ring of benzyl halides. The yields range from moderate to high.

• 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.

  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。

  An iodine-mediated oxidative cyclization reaction between 2-(pyridin-2-yl)acetate derivatives and different alkynes has been developed, which provides regioselective and chemoselective syntheses of multiply substituted indolizines under modified reaction conditions. Plausible mechanisms have been proposed to explain the selective syntheses of indolizines. This protocol can be also applied to the stepwise

  Pd‐catalyzed desulfitative approach to C‐3 arylation of indolizine derivatives has been developed, and the protocol uses readily available arylsulfonyl chlorides as the arylation reagent under nitrogen. This transformation was performed in a mixed solvent of 1‐methyl‐2‐pyrrolidone and dimethoxyethane using simple triphenylphosphine as a ligand, which provides a new method for the C‐3 arylation of indolizines
