Au-Catalyzed Cross-Coupling of Arenes via Double C-H Activation

The first methodology for Au(I/III)-catalyzed oxidative cross-coupling of arenes via double C-H activation has been developed. The reaction is fully selective for the cross-coupling between electron-rich hetero-/carbocyclic arenes and electron-poor arenes bearing relatively acidic C-H bonds. The inherently high cross-selectivity of the system obviates the need for directing groups or a large excess of one of the coupling partners.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 6-Methoxyindole, you can also check out more blogs about3189-13-7

Acyl Phosphonates: Good hydrogen bond acceptors and ester/amide equivalents in asymmetric organocatalysis

This study demonstrates that unsaturated acyl phosphonates are excellent hydrogen-bond acceptors in enantioselective organocatalysis. By employing chiral thioureas orsquaramides as catalysts, the acyl phosphonates are effectively coordinated and activated by hydrogen bonding, thereby providing successful relay of the chirality from the catalyst to the substrate. A variety of highly stereoselective conjugate additions to alpha,beta-unsaturated acyl phosphonates were performed, using different carbon-based nucleophiles such as oxazolones, indoles, and 1,3-dicarbonyl compounds. The reaction concept has been developed to be a double nucleophilic reaction, and it is shown that the acyl phosphonates serve as masked ester or amide equivalents, which upon quenching with the second nucleophile generate the parent structures in situ. Accordingly, formal C-C bond formation reactions of ester and amide substrates are achieved, affording a broad spectrum of optically active conjugate adducts in good yields and excellent enantioselectivities. Based on the experimental results, the mechanisms for the different reactions are discussed, including the approach of the oxazolones, indoles, and 1,3-dicarbonyl compounds to the acyl phosphonate coordinated to the catalyst and the role of the catalyst for the reaction course of the nucleophiles.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4837-90-5, help many people in the next few years.Formula: C9H9NO

Atom-economical selenation of electron-rich arenes and phosphonates with molecular oxygen at room temperature

Organoselenium and selenophosphorus compounds are ubiquitously found in biologically active compounds, agrochemicals, functionalized materials etc. Although selenium is a micronutrient and an essential trace element, its contamination/consumption in higher concentrations is extremely dangerous. However, most of the previous selenation reactions generate toxic selenium waste as a by-product. Thus development of green synthetic protocols of these compounds is in high demand. We report herein a mild base-catalyzed cross-dehydrogenative coupling (CDC) between electron-rich arenes and phenylselenol to afford 3-selenylindole or selenylated phenols under air at room temperature. Interestingly, in the presence of a base and oxygen, the phenylselenol is converted into the diphenyldiselenide and provides almost quantitative yield. Similarly, a mild synthesis of selenophosphates was also achieved from the corresponding diorganyldiselenide or phenylselenols and nucleophilic phosphonates in a “dump and stir” manner under an oxygen balloon without a base or catalyst. From the preliminary mechanistic studies for selenation of indoles and phosphonates with TEMPO and EPR of the reaction mixture, it was evident that the reaction proceeds through the anionic pathway, which is in sharp contrast to the previous literature. The present reactions proceed smoothly under the mild conditions, furnishing high to almost quantitative yields in several cases. The reaction is easily scaled up to gram scale and has been demonstrated for the synthesis of an anti-HIV zidovudine (AZT) analogue.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Recommanded Product: 4-Cyanoindole, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 16136-52-0

An environmentally friendly protocol for oxidative halocyclization of tryptamine and tryptophol derivatives

An environmentally friendly and efficient protocol (KX/oxone) for oxidative halocyclization of tryptamine/tryptophol derivatives was developed and demonstrated with 28 examples and concise total synthesis of cyclotryptamine alkaloid protubonines A and B. The distinct advantage of this protocol over all previous methods is that no organic byproduct is generated from a halogenating agent or oxidant, thus greatly reducing the environmental impact of halocyclization and facilitating the post-reaction purification.

Inhibitors of HIV-1 attachment. Part 2: An initial survey of indole substitution patterns

The effects of introducing simple halogen, alkyl, and alkoxy substituents to the 4, 5, 6 and 7 positions of 1-(4-benzoylpiperazin-1-yl)-2-(1H-indol-3-yl)ethane-1,2-dione, an inhibitor of the interaction between HIV gp120 and host cell CD4 receptors, on activity in an HIV entry assay was examined. Small substituents at C-4 generally resulted in increased potency whilst substitution at C-7 was readily tolerated and uniformly produced more potent HIV entry inhibitors. Substituents deployed at C-6 and, particularly, C-5 generally produced a modest to marked weakening of potency compared to the prototype. Small alkyl substituents at N-1 exerted minimal effect on activity whilst increasing the size of the alkyl moiety led to progressively reduced inhibitory properties. These studies establish a basic understanding of the indole element of the HIV attachment inhibitor pharmacophore.
