Metal and acid-free visible light-mediated Friedel-Crafts alkylation reactions of indole with anilines

Metal and acid-free visible light-induced Friedel-Crafts C3-alkylation reactions of indole derivatives were developed using N,N-dimethylanilines as the carbon source. A cheap and readily available organic dye, Rose Bengal, was applied as the photocatalyst. This environmentally friendly transformation afforded C3-alkylated indoles in moderate to good yields under mild conditions. (C) 2018 Elsevier Ltd. All rights reserved.

Synthesis and antiproliferative activity of salicylidenehydrazones based on indole-2(3)-carboxylic acids

A series of indole-2(3)-carboxylic acid hydrazones were synthesized and their antiproliferative activity was studied for the K562 leukemia, MCF7 breast adenocarcinoma, and HCT116 colon carcinoma cell lines and resistant HCT116p53KO subline in order to preliminary screen biological properties and to reveal the role of the aldehyde fragment and heterocycle in the ability of compounds to inhibit tumor growth.

Switchable regioselection of C-H thiolation of indoles using different TMS counterions

A switchable regioselectivity in C-H thiolation reaction by simply swapping the counteranions of TMS is reported here for the first time. An exclusive C3-H thiolation of indoles with sodium arylsulfinates was achieved in the presence of TMSCl as a promoter. In contrast, with the use of TMSOTf instead of TMSCl under otherwise identical conditions, a regiospecific C2-H thiolation of indoles was realized with the same set of substrates.

Gold-Catalyzed Oxidative Arylations of 3-Butyn-1-ols and 2-Propyn1-ols with Nitrones to Yield Distinct Fused Indoles Bearing a Heterocyclic Ring

The catalytic formation of various fused indoles from the nitrone oxidations of 1-substituted n-yn-1-ols (n = 2, 3) is described. For 3-butyn-1-ols, the oxidations yield tetrahydropyrano[4,3-b]indoles, whereas 2-propynols deliver tetrahydro-[1,2]oxazino[5,4-b]indoles efficiently. When styryl nitrones were tested on 2-propyn-1-ols, dihydrooxazolo[3,4-a]indoles were produced efficiently. We postulate that the formation of these fused indoles arises from a common mechanism, involving a [3,3]-sigmatropic shift of an initial alkenyl gold intermediate to furnish an oxoarylation before preceding to these fused indoles.

Abatement of arsenic-induced phytotoxic effects in rice seedlings by an arsenic-resistant Pantoea dispersa strain

Population detonation and rapid industrialization are the major factors behind the reduction in cultivable land that affects crop production seriously. This situation is further being deteriorated due to the negative effects of abiotic stresses. Under such conditions, plant growth-promoting rhizobacteria (PGPR) are found to improve crop production which is essential for sustainable agriculture. This study is focused on the isolation of potent arsenic (As)-resistant PGPR from the agricultural land of West Bengal, India, and its application to reduce As translocation in rice seedlings. After screening, an As-resistant PGPR strain AS18 was identified by phenotypic characters and 16S rDNA sequence-based homology as Pantoea dispersa. This strain displayed nitrogen fixation, phosphate solubilization, 1-aminocyclopropane-1-carboxylic acid deaminase (ACCD) activity, indole-3-acetic acid (IAA) production, in addition to As (III) resistance up to 3750 mu g/mL. The As removal efficiency of this strain was up to 93.12% from the culture medium as evidenced by AAS. The bioaccumulation property of AS18 strain was further validated by TEM-EDAX-XRD-XRF-FTIR studies. This strain showed significant morpho-biochemical improvements including antioxidant enzymatic activities and As-minimization in plant (rice) cells. Thus, being an As-resistant potent PGPR, AS18 strain is expected to be applied in As-spiked agricultural fields for bioremediation and phytostimulation.

Highly Diastereo- and Enantioselective Synthesis of Cyclohepta[b]-indoles by Chiral-Phosphoric-Acid-Catalyzed (4+3) Cycloaddition

A highly enantio- and diastereoselective formal (4+3) cycloaddition of 1,3-diene-1-carbamates with 3-indolylmethanols in the presence of a chiral phosphoric acid catalyst is reported. The approach described herein provides efficient access to 6-aminotetrahydrocyclohepta[b]indoles in good yields with mostly complete diastereoselectivity and excellent levels of enantioselectivity (> 98:2 dr and up to 98% ee). Mild reaction conditions, facile scale-up, and versatile derivatization highlight the practicality of this methodology. A mechanistic study suggests that cycloaddition occurs in a stepwise fashion, after the formation of an ion pair between the chiral catalytic phosphate and the intermediate carbocation.
