I2O5 promoted iodosulfenylation of indoles under metal-free conditions

A mild, efficient, and metal-free strategy to construct 2-iodo-3-arylthioindoles was developed via I2O5-promoted iodosulfenylation of indoles utilizing simple, cheap and easily available thiophenols as sulfur sources.

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.

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 1200-22-2 help many people in the next few years. HPLC of Formula: C8H14O2S2.

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.

Indole Signaling at the Host-Microbiota-Pathogen Interface

Microbial establishment within the gastrointestinal (GI) tract requires surveillance of the gut biogeography. The gut microbiota coordinates behaviors by sensing host-or microbiota-derived signals. Here we show for the first time that microbiota-derived indole is highly prevalent in the lumen compared to the intestinal tissue. This difference in indole concentration plays a key role in modulating virulence gene expression of the enteric pathogens enterohemorrhagic Escherichia coli (EHEC) and Citrobacter rodentium. Indole decreases expression of genes within the locus of enterocyte effacement (LEE) pathogenicity island, which is essential for these pathogens to form attaching and effacing (AE) lesions on enterocytes. We synthetically altered the concentration of indole in the GI tracts of mice by employing mice treated with antibiotics to deplete the microbiota and reconstituted with indole-producing commensal Bacteroides thetaiotaomicron (B. theta) or a B. theta Delta tnaA mutant (does not produce indole) or by engineering an indole-producing C. rodentium strain. This allowed us to assess the role of self-produced versus microbiota-produced indole, and the results show that decreased indole concentrations promote bacterial pathogenesis, while increased levels of indole decrease bacterial virulence gene expression. Moreover, we identified the bacterial membranebound histidine sensor kinase (HK) CpxA as an indole sensor. Enteric pathogens sense a gradient of indole concentrations in the gut to probe different niches and successfully establish an infection. IMPORTANCE Pathogens sense and respond to several small molecules within the GI tract to modulate expression of their virulence repertoire. Indole is a signaling molecule produced by the gut microbiota. Here we show that indole concentrations are higher in the lumen, where the microbiota is present, than in the intestinal tissue. The enteric pathogens EHEC and C. rodentium sense indole to downregulate expression of their virulence genes, as a read-out of the luminal compartment. We also identified the bacterial membrane-bound HK CpxA as an indole sensor. This regulation ensures that EHEC and C. rodentium express their virulence genes only at the epithelial lining, which is the niche they colonize.

MOFs Extend the Lifetime of Pd(II) Catalyst for Room Temperature Alkenylation of Enamine-Like Arenes

The synthesis of pharmaceutically relevant scaffolds, such as substituted indoles or uracils, through the alkenylation of the enamine-like aromatic C-H bond is performed at room temperature using catalytic amounts of Pd(OAc)(2) in the presence of redox active, stable and reusable metalorganic microporous frameworks. This is the first time that redox/acid active sites in the porous, nontoxic and earth abundant robust MOF-74 platform are used to avoid the fast deactivation of the cationic Pd species working under ambient conditions.

Amberlite IRA-400 Cl resin catalyzed synthesis of secondary amines and transformation into N-((1H-indol-3-yl) (heteroaryl) methyl)-N-heteroaryl benzenamines and bis-indoles via multicomponent reaction

A one-pot Amberlite IRA-400 Cl resin catalyzed the in-situ generation of imines from various aldehydes and primary amines followed by reduction with sodium borohydride affording corresponding secondary amines. The secondary amines thus obtained were utilized for the IRA-400 Cl resin catalyzed multicomponent synthesis of 3-aminoalkylated indoles using a number of aldehydes and indole. Mild condition, easy work-up, and environmentally benign nature of the synthetic strategy make it both practical and attractive. (C) 2016 King Saud University.
