A simple and efficient approach for the preparation of substituted indoles and isoquinolones via a nickel-catalyzed Larock-type heteroannulation reaction is reported. This transformation employed air-stable and inexpensive Ni(dppp)Cl-2 as a precatalyst and Et3N as a mild base. Moreover, the reaction occurs efficiently under mild conditions, and a wide range of substituted indoles and isoquinolones bearing various functional groups are obtained in moderate to excellent yields.

Application of 148849-67-6, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 148849-67-6 is helpful to your research.

Ethnopharmacological relevance: The leaf of Sarcocephalus latifolius is known to be used traditionally by the Fulanis in Nigeria to deworm animals. As helminthosis remains a major constraint to profitable livestock production worldwide, a precarious situation aggravated by the advent of resistant parasites, the discovery of new anthelmintics is a priority, necessitating exploration of medicinal plants for their anthelmintic principles. Aim of the study: To identify and characterise compounds with anthelmintic activity from the leaf of Sarcocephalus latifolius. Materials and methods: Powdered S. latifolius leaves were extracted by successive maceration with n-hexane, chloroform and acetone. The dried extracts were evaluated for anthelmintic activity against Haemonchus placei adult worms, and the most active extract was subjected to bioassay-guided chromatographic separations. The isolated compounds were evaluated for cytotoxicity against the mammalian HeLa and MC3T3-E1 cell lines, using alamar blue and CellTitreGlo (TM) to quantify cell viability. LC50 values were computed from the in vitro anthelmintic activity data by fitting to a non-linear regression equation (variable slope). Isolated compounds were characterized using spectroscopic and mass spectrometric analyses. Results: Anthelmintic activity LC50 values for n-hexane, chloroform and acetone extracts were 47.85, 35.76 and 5.72 (mg/mL), respectively. Chromatographic separation of acetone extract afforded two bioactive epimers, identified as vincosamide (LC50 14.7 mg/mL) and strictosamide (LC50 12.8 mg/mL). Cytotoxicity evaluation showed that, below 200 mu g/mL (400 mu M), neither compound was toxic to the HeLa or MC3T3-E1 cells. Conclusion: Vincosamide and strictosamide could serve as novel scaffolds for the development of anthelmintic derivatives with improved potency and helminth selectivity.

In a document, author is Zhang, Ming-Zhi, Quality Control of Ivabradine hydrochloride.

Pimprinine and streptochlorin are indole natural products produced by many species of organisms, and they are reported to possess a wide range of biological activities, such as anticancer, antiviral, antifungal activity and so on. In this study, three series of pimprinine derivatives or analogs were efficiently synthesized under the optimized methods. Biological assays conducted at Syngenta firstly indicated the pimprinine derivatives or analogs possessed potential herbicidal and insecticidal activity, and this is highlighted by compounds 21g, 21h, 21i, 21j, 21l, 22h, 22i and 23h, they possessed significant biological activity as well as broad spectrum. Meanwhile, compounds with benzothiophene-oxazole core (21h, 22h and 23h), showed effective nematicidal activity in primary screening. Compounds 21g and 21i were identified as the most promising lead structures for further study. (C) 2020 Elsevier Ltd. All rights reserved.

IntraMolecular Diels-Alder Reactions of Vinylarenes and Alkynyl Arenes (the IMDAV Reaction) (vol 53, pg 893, 2021)

This comprehensive review summarizes the published literature data concerning the intramolecular Diels-Alder reactions of vinylarenes (the IMDAV reaction) and alkynyl arenes from 1970 to 2019, and covers mainly intramolecular [4+2] cycloaddition reactions of vinyl- or acetylene-substituted furans, thiophenes, pyrroles, indoles, imidazoles, benzenes, and naphthalenes, in which the unsaturated substituent is linked directly to an arene moiety. The selected area of the Diels-Alder reaction differs from other forms of [4+2] cycloadditions due to the uniqueness of the diene fragment, which, along with an exocyclic multiple bond, includes the double bond of an aromatic or heteroaromatic nucleus in its system. Thus, during the formation of the [4+2] cycloaddition intermediate, the aromaticity of furan, thiophene and even benzene rings is broken, leading, as a rule, to the formation of heterocyclic structures rarely accessible by other methods, in contrast to the majority of intermolecular Diels-Alder reactions, with the highest degree of chemo-, regio-, and diastereoselectivity. Therefore, the IMDAV approach is often used for the synthesis of naturally occurring and bioactive molecules, which are also discussed in this review alongside other applications of this reaction. Whenever possible, we have tried to avoid examples of radical, photochemical, oxidative, precious-metal-complex-catalyzed cyclizations and other types of formal [4+2] cycloadditions, focusing on thermal Diels-Alder reactions in the first step, according to the classical mechanism. The second stage of the process, aromatization, is unique for many initial substrates, and hence considerable attention in this overview is given to the detailed description of the reaction mechanisms. 1 Introduction 2 IMDAV Reactions of Vinylfurans 2.1 Alkenes as Internal Dienophiles 2.2 Alkynes and Allenes as Internal Dienophiles 3 IMDAV Reactions of Vinylthiophenes 3.1 Alkenes as Internal Dienophiles 3.2 Alkynes as Internal Dienophiles 4 IMDAV Reactions of Vinylbenzothiophenes 5 IMDAV Reactions of Vinylpyrroles 6 IMDAV Reactions of Vinylindoles 6.1 Alkenes as Internal Dienophiles 6.2 Alkynes as Internal Dienophiles 7 IMDAV Reactions of Styrenes and Vinylnaphthalenes 7.1 Alkenes as Internal Dienophiles 7.2 Alkynes as Internal Dienophiles 7.3 Alkynes as Internal Dienophiles in Aryl Acetylenes (the Intramolecular Dehydro Diels-Alder Reaction) 8 IMDAV Reactions of Vinylimidazoles, Vinylisoxazoles and Vinylpyridines 9 Conclusion 10 Abbreviations
