The article was titled 《Palladium-Mediated Oxidative Annulation of δ-Indolyl-α,β-Unsaturated Compounds toward the Synthesis of Cyclopenta[b]indoles and Heterogeneous Hydrogenation To Access Fused Indolines》. The information in the text is summarized as follows:

The cyclopenta[b]indole moiety represents a key skeletal unit in several natural and synthetic compounds that exhibit diverse biol. properties. We described herein a two-step sequence for synthesizing cyclopenta[b]indoles with great structural diversity in overall yields up to 37%. The key step was a palladium-catalyzed oxidative annulation of 3-alkylindoles (Fujiwara-Moritani reaction). The obtained cyclopenta[b]indoles were used as substrates in heterogeneous hydrogenation reactions to afford new fused indolines in moderate yields. An acid-catalyzed intramol. cyclization of three such indolines gave tetracyclic lactams in 89, 90, and 61% yields.5-Fluoro-1H-indole(cas: 399-52-0Safety of 5-Fluoro-1H-indole) was used in this study.

Application In Synthesis of 5-Fluoro-1H-indole And the article was included in Applied Catalysis, B: Environmental in 2020. The article conveys some information:

Task-specific design and construction of conjugated microporous polymers (CMPs) for classic organic transformation is highly significant but challenging. Herein, we report strategy to promote charge transfer in CMPs using phenothiazine unit as a core and commonly used building blocks (carbazole/benzene) as the linker. Featuring by wide visible-light absorption, narrow optical bandgap, and facilitated charge transfer, phenothiazine-core CMPs exhibited superior photocatalytic performance towards Ugi-type reaction and aerobic selenation of indoles compared with those phenothiazine-free counterparts and commonly reported photocatalysts. Furthermore, the photocatalytic enhancement achieved in the designed CMPs system represents a substantial advance and verifies the viability of a simple strategy to tailor the photophys. properties of CMPs, which may facilitate the design of new photocatalysts.5-Fluoro-1H-indole(cas: 399-52-0Application In Synthesis of 5-Fluoro-1H-indole) was used in this study.

《Ni-Catalyzed Traceless, Directed C3-Selective C-H Borylation of Indoles》 was written by Tian, Ya-Ming; Guo, Xiao-Ning; Wu, Zhu; Friedrich, Alexandra; Westcott, Stephen A.; Braunschweig, Holger; Radius, Udo; Marder, Todd B.. Computed Properties of C8H6FN And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

A highly efficient and general protocol for traceless, directed C3-selective C-H borylation of indoles with [Ni(IMes)2] as the catalyst is reported. Activation and borylation of N-H bonds by [Ni(IMes)2] is essential to install a Bpin moiety at the N-position as a traceless directing group, which enables the C3-selective borylation of C-H bonds. The N-Bpin group which is formed is easily converted in situ back to an N-H group by the oxidiative addition product of [Ni(IMes)2] and in situ-generated HBpin. The catalytic reactions are operationally simple, allowing borylation of a variety of substituted indoles with B2pin2 in excellent yields and with high selectivity. The C-H borylation can be followed by Suzuki-Miyaura cross-coupling of the C-borylated indoles in an overall two-step, 1-pot process providing an efficient method for synthesizing C3-functionalized heteroarenes.

SDS of cas: 399-52-0. The article was titled 《Cu/Chiral Phosphoric Acid-Catalyzed Asymmetric Three-Component Radical-Initiated 1,2-Dicarbofunctionalization of Alkenes》. The information in the text is summarized as follows:

An asym. intermol., three-component radical-initiated dicarbofunctionalization of 1,1-diarylalkenes with diverse carbon-centered radical precursors and electron-rich heteroaromatics by a copper(I) and chiral phosphoric acid cooperative catalysis strategy has been developed, providing straightforward access to chiral triarylmethanes bearing quaternary all-carbon stereocenters with high efficiency as well as excellent chemo- and enantioselectivity. The key to success is not only the introduction of a sterically demanding chiral phosphoric acid to favor radical difunctionalization over the otherwise remarkable side reactions but also the in situ generation of carbocation intermediates from benzylic radical to realize asym. induction with the aid of a removable hydroxy directing group via cooperative interactions with chiral phosphate. D. functional theory calculations elucidated the critical chiral environment created by the hydrogen-bonding and ion-pair interactions between the chiral phosphoric acid catalyst and substrates, which leads to the enantioselective C-C bond formation.

The use of an operationally convenient and stable silicon reagent (octamethyl-1,4-dioxacyclohexasilane, ODCS) for the selective silacyclization of (hetero)arenes via twofold C-H activation is reported, giving oxadisilole-annelated indole, carbazoles and arene phosphine derivatives This method is compatible with N-containing heteroarenes such as indoles and carbazoles of varying complexity. The ODCS reagent can also be utilized for silacyclization of other types of substrates, including tertiary phosphines and aryl halides. A series of mechanistic experiments and d. functional theory (DFT) calculations were used to investigate the preferred pathway for this twofold C-H activation process.5-Fluoro-1H-indole(cas: 399-52-0Recommanded Product: 399-52-0) was used in this study.

Palladium-catalyzed direct C-H activation of indole benzenoid moiety has been achieved in the past decade. However, palladium-catalyzed remote C-H activation of indoles is rare. Herein, we report a challenging palladium-catalyzed remote C4-H phosphonylation of indoles by a radical approach. The method provides access to a series of C4-phosphonylated indoles, including tryptophan and tryptophan-containing dipeptides, which are typically inaccessible by direct C4-H activation due to its heavy reliance on C3 directing groups. Notably, unexpected C6-phosphonylated indoles were obtained through blocking of the C4 position. The preliminary mechanistic studies indicated that the reactions may proceed via a C7-palladacycle/remote-activation process. Based on the strategy, examples of remote C4-H difluoromethylation with BrCF2COOEt are also presented, suggesting that the strategy may offer a general blueprint for other cross-couplings.
