Copper-Catalyzed Three-Component Reaction for Regioselective Aryl- and Heteroarylselenation of Indoles using Selenium Powder

A new and efficient copper-catalyzed C3 aryl- and heteroarylselenation of indoles employing selenium powder has been developed. The advantages of this chemistry involve the use of cheap selenating reagents, tolerance of a variety of functional groups, and practicality. In addition, this protocol has been further elaborated in an intramolecular phenylselenation of a (hetero) aryl C-H bond to construct an important motif of benzoselenopheno[3,2-b]indole. A preliminary mechanism study suggests that the reaction starts with a Ullman-type selenation between aryl iodides and selenium, followed by an oxidative cross-coupling with indole. The utility of this method has been demonstrated in an efficient gram-scale synthesis and an application to the synthesis of tubulin polymerization inhibitor.

Asymmetric Friedel-Crafts Alkylation of Indoles with Trifluoromethyl Pyruvate Catalyzed by a Dinuclear Zinc Catalyst

A bimetallic cooperative catalysis model has been reported for the asymmetric Friedel-Crafts (F-C) alkylation of indoles with trifluoromethyl pyruvates using Trost’s intramolecular dinuclear zinc complex as the catalyst. This dinuclear zinc catalyst was prepared in situ by reacting the chiral ligand (S,S)-L2b with 2 equiv of ZnEt2. A series of trifluoromethyl alcohol and indole-containing biological compounds were formed in moderate to good yields (up to 95%) with good enantioselectivity (up to 88% enantiomeric excess (ee)) in the presence of 10 mol % catalyst under mild conditions. A synergistic transition state model was proposed to explain the origin of the asymmetric induction.

A magnetic metal-organic framework as a highly active heterogeneous catalyst for one-pot synthesis of 2-substituted alkyl and aryl(indolyl)kojic acid derivatives

A novel magnetic metal-organic framework, NiFe2O4@MOF-5, has been prepared and characterized using spectroscopic, microscopic, and magnetic techniques (FT-IR, XRD, TEM, SEM, EDX, and VSM). This magnetically separable catalyst exhibited high catalytic activity for the synthesis of a variety of 2-substituted alkyl and aryl(indolyl)kojic acid derivatives via a one-pot, three-component reaction of aldehyde, indole, and kojic acid under solvent-free conditions. The catalyst can be easily magnetically separated and exhibits significant recyclability, with no significant loss of activity after six consecutive runs.

52415-29-9, (a) 6-Bromo-1-methylindole STR25 Sodium hydride (4.10 g of a 60% dispersion in paraffin wax) was added to a stirred solution of 6-bromoindole (10 g, 51.3 mmol) in tetrahydrofuran (10 ml) at 0 C. under a nitrogen atmosphere. After 1 hour iodomethane (6.38 ml, 102.6 mmol) was added and the cooling bath removed. After 12 hours methanol was added dropwise until effervescence ceased and then the solvent was removed in vacuo. The thick residue was diluted with dichloromethane and washed first with water then with brine. The organic layer was dried (magnesium sulphate) and concentrated in vacuo to give a dark yellow oil. Filtration through a plug of silica with 90% hexane/10% ethyl acetate as eluant gave the subtitle compound as a pale yellow oil (10.5 g). 1 H NMR (300 MHz, CDCl3): delta=3.75 (d, 3 H), 6.40 (d, 1 H), 7.00 (d, 1 H), 7.20 (d, 1 H), 7.50 (d, 1 H), 7.45 (s, 1 H).
