Copper-Catalyzed Chemodivergent Cyclization of N-(ortho-alkynyl)aryl-Pyrrole and Indoles

Herein, we described an efficient copper-catalyzed chemo-divergent tandem reaction of N-(ortho-alkynyl)aryl-pyrrole and (iso)indoles, delivering ring-fused N-heterocycles in good yields in an atom-economical manner. N-(ortho-alkynyl)aryl-pyrrole and indoles undergo the tandem cyclization/migration reaction, in which the group at 2-position was migrated to 3-position. In contrast, the dearomative cyclization of N-(ortho-alkynyl)aryl-isoindoles would occur to deliver the N-fused tetracyclic products efficiently.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 138530-94-6. SDS of cas: 138530-94-6.

Ru-catalyzed oxidative dearomatization-hydroxylation of N-Boc indoles

Ruthenium catalyzed oxidative dearomatization-hydroxylation of N-Boc indoles for the synthesis of 2-hydroxyindolin-3-ones was described. The N-Boc indoles can be transformed into 2-hydroxyindolin-3-ones with RuCl3 center dot 3H(2)O as catalyst, p-toluenesulfonic acid (TsOH center dot H2O) as promoter and tert-butyl peroxide (TBHP, 3.0 equiv) as oxidant in acetonitrile. The mechanism had been proposed on the basis of control experiments and isolation of intermediate.

Indole derivatives as multifunctional drugs: Synthesis and evaluation of antioxidant, photoprotective and antiproliferative activity of indole hydrazones

Two series of indole derivatives 4-17, 20-22 were easily prepared and assayed for their radical-scavenging ability. Arylidene-1H-indole-2-carbohydrazones showed different extent antioxidant activity in DPPH, FRAP and ORAC assays. Good antioxidant activity is related to the number and position of hydroxyl groups on the arylidene moiety as well as to the presence of methoxy or 4-(diethylamino) group. On the contrary low antioxidant activity is showed by the isomeric 1H-indol-2-yl(methylene)-benzohydrazides. Furthermore, hydrazones 4-17 showed photoprotective capacities with satisfactory in vitro SPF as compared to the commercial PBSA sunscreen filter. The indole 16 and 17, showing the best antioxidant and photoprotective profile, were included in different formulation and their topical release was evaluated. Varying the formulation composition, it was possible to optimize skin adsorption and solubility of the active indole in the formulation. The antiproliferative effect of the hydrazones 4-17 was tested on human erythroleukemia K562 and melanoma Colo-38 cells. Hydrazones 11, 16 and 17 showed growth inhibition at sub micromolar concentrations on both cell lines. These results indicate indole hydrazones as potential multifunctional molecules especially in the treatment of neoplastic diseases being the good antioxidant properties of 16 and 17 correlated to their high antiproliferative activity.

Chitosan Cu-Catalyzed C3-Sulfenylation of Indoles with Sulfur Powder and Aryl Iodides

Aiming at the problem that the catalyst can not be recovered during the construction of the C-S bond in the indole ring with sulfur powder as the sulfur source, 2-pyridinecarboxylic acid modified chitosan (PACS) catalyst with different type of copper was prepared, which was used to catalyze the three-component reaction of indole, sulfur powder and iodobenzene to prepare C-3 thioether-based indole in a one-pot method. The reaction yield is as high as 92%, and the substrate has good applicability. The most suitable catalyst [PACS(d;Cu(OAc)(2)] was characterized and analyzed by thermogravimetric analysis (TGA), scanning electron microscope(SEM), X-ray photoelectron spectroscopy(XPS), etc. It shows that the catalyst has the advantages of no additional ligand, easy separation and reusable.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 138530-94-6, in my other articles.
