  Pd-Catalyzed Tandem C−N/C−C Coupling of gem-Dihalovinyl Systems:  A Modular Synthesis of 2-Substituted Indoles

  摘要：

  2-Substituted indoles were synthesized via a Pd-catalyzed tandem C-N/Suzuki-Miyaura coupling from readily prepared ortho-gemdihalovinylanilines. Optimal conditions used a Pd(OAC)(2)/S-Phos catalyst in the presence of (K3PO4H2O)-H-. and an organoboron reagent, which included boronic acids, esters, alkyl 9-BBN derivatives, and trialkylboranes. Yields of the desired indoles were good to excellent using low catalyst loadings (typically 1 mol %).

  日期：2024.3.1

  Readily available N-carbamoyl indolines can be converted into highly valuable 2-alkenyl and 2-alkyl indoles in a one-pot reaction, through an autotandem catalytic cascade promoted by an iridium complex. The process entails a dehydrogenation reaction initiated by an iridium-promoted C(sp3)–H activation, the addition of the resulting indole to an alkyne -or alkene-partner, and a spontaneous loss of the carbamoyl

  通过铱络合物促进的自动串联催化级联，可以在一锅反应中将容易获得的N-氨基甲酰二氢吲哚转化为高价值的 2-烯基和 2-烷基吲哚。该过程需要由铱促进的 C(sp 3 )–H 活化引发的脱氢反应，将所得吲哚添加到炔烃或烯烃伴侣上，以及氨基甲酰基导向基团的自发损失。有趣的是，所得的C2-烯基吲哚可以参与由C-H活化引发的各种金属催化环化，包括正式的[4 + 1]和[4 + 2]环加成，以及交叉脱氢环化，从而使获得功能丰富的含氮杂环集合的不同途径。
