A micellar catalysis strategy applied to the Pd-catalyzed C-H arylation of indoles in water

The selective control over multiple competing C-H sites would enable straightforward access to functionalized indoles. In this context, we report here a modular and selective C-H arylation of indoles following the micellar catalysis approach using the third generation designer surfactant SPGS-550-M in the presence of 1 mol% of [(cinnamyl)PdCl](2) under mild conditions. Thus, access to high value C-arylated (C-3 and C-2) indoles was achieved fulfilling the triple bottom line philosophy of green chemistry. The nature of the phosphine ligand was found to be critical for achieving site-selectivity, DPPF and DPPP being the most effective in promoting the arylation at C-3-H and C-2-H, respectively. The reaction is scalable and offers high chemo- (C vs. N) and regio-selectivity (C-3 vs. C-2) with a wide range of functional group tolerance. The surfactant aqueous solution can be recycled and reused without compromising on product yields.

Copper-Catalyzed Indole-Selective C-N Coupling Reaction of Indolyl(2-alkoxy-phenyl)iodonium Imides: Effect of Substituent on lodoarene as Dummy Ligand

A monoalkoxy phenyl group as a dummy ligand on indolyl(aryl)iodonium imides, which is related to the N-I bonding hypervalent iodine(III) compound, for the copper-catalyzed indole-selective C-N coupling reaction was designed to provide 3-bissulfonimido-indole derivatives in high yields.

Pseudomonas entomophila PE3 and its exopolysaccharides as biostimulants for enhancing growth, yield and tolerance responses of sunflower under saline conditions

Evaluation of plant growth promoting bacteria and the associated metabolites under saline conditions can be a potential eco-friendly remediation and productivity enhancement strategy. Salt-tolerant Pseudomonas entomophila PE3 was isolated from saline soil and screened for plant growth promoting (PGP) traits. The isolate produced indole acetic acid (IAA), gibberellic acid (GA), exopolysaccharides (EPS) and siderophore along with the potential to solubilize potassium (K), zinc (Zn) and phosphorus (P). Maximum stimulation of PGP attributes was recorded at 2% NaCl concentration. To determine the role of EPS, their composition was analyzed (at different salt concentrations) and comparison was done to determine the changes upon exposure to salinity. EPS was found to be rich in carbohydrates, proteins and phenolic compounds. The extracted EPS were also found to possess salt-tolerance properties including antioxidant, hydroxyl scavenging activity, reducing power, emulsification and flocculation potential, and Na+ accumulation ability. Interestingly, the salt tolerance properties of EPS were enhanced upon exposure to salinity (2% NaCl). Finally, EPS based bioformulation of isolate PE3 was checked through field assay in saline soil. With promising results on growth promotion and improved salinity tolerance attributes of inoculated sunflower plants, the bioformulation of PE3 amended with EPS can be a breakthrough for remediation of saline-agroecosystems.

Unified enantioselective total syntheses of (-)-scholarisine G, (+)-melodinine E, (-)-leuconoxine and (-)-mersicarpine

A unified strategy enabled the enantioselective syntheses of (-)-scholarisine G, (+)-melodinine E, (-)-leuconoxine and (-)-mersicarpine from a common 2-alkylated indole intermediate bearing an all-carbon quaternary stereogenic center.

Lactone (+)-8 was prepared via a palladium-catalyzed intermolecular asymmetric allylic alkylation. The unified and protecting-group-free reaction sequences allowed the synthesis of these alkaloids in a maximum of 10 steps and with high efficiency.

Identification and functional study of an iif2 gene cluster for indole degradation in Burkholderia sp. IDO3

Burkholderia sp. IDO3 is an indole-degrading bacterium isolated from activated sludge. A previous genomic clone library assay identified an iif1 gene cluster for indole metabolism in strain ID03. To further explore the underlying indole degradation mechanisms, the complete genome of strain IDO3 was sequenced (8,003,806 bp). The genome contained three circular chromosomes and one plasmid, and 7550 genes were predicted. Interestingly, in addition to iif1 on chromosome 3, bioinformatic analyses identified a second indole oxygenase gene cluster, iif2, on chromosome 1. Both iif clusters were up-regulated in response to indole. Heterologous expression of iifC1D1 and iifC2D2 in Escherichia coli BL21(DE3) demonstrated that these genes were capable of oxidizing indole to indigo. Gene knockout assays provided additional evidence that iifC2 played crucial roles in indole metabolism. In addition, we identified a novel gene (iifF) in the iif2 cluster. This gene was shown to encode an isatin hydrolase. IifF was expressed in E. coli, and a purified his-tagged enzyme preparation was obtained. IifF converted isatin to isatinate with K-m of 4.4 +/- 0.7 mu M and k(cat) of 95.5 +/- 4 s(-1). This is the first study to show that indole can be degraded by two iif gene clusters, and that isatin hydrolase is involved in indole metabolism, improving our understanding of indole metabolic processes.

Isolation and Screening of Indigenous Rhizobia from BlackGram Cultivated in Fallow Rice Soils for Plant Growth Promoting Traits

Bio fertilisers are relatively safer, environmentally friendly and a cost-effective approach to chemical fertiliser usage. The selection of bacterial strains with multiple beneficial characteristics is important to maximise their effectiveness on the host plant. In the present study, four native and indigenous rhizobial strains (VM-2, VM-8, VM-9 and VM-15) were isolated from root nodules of blackgram (Vignamungo) cultivated in fallow rice soils of Andhra Pradesh, India. All the four strains were screened in vitro for their plant growth-promoting (PGP) characteristics viz. production of indole acetic acid (IAA), exopolysaccharide (EPS), hydrogen cyanide (HCN) and phosphate solubilisation. The results indicated that the rhizobial strains varied in their plant growth promoting activities. All the four strains produced IAA, EPS and also solubilised the insoluble phosphate. The amount of IAA produced varied from strain to strain and relatively high amounts were recorded in VM-8 (43.4 mu g/ml) followed by VM-15 with 43.1 mu g/ml. Maximum EPS production was recorded in VM-9 (527 mg/ml) followed by VM-8 (483 mg/ml). The phosphate solubilisation efficiency of Rhizobium strains on solid media ranged between 16% and 17%. In liquid medium, strain VM-2 recorded maximum solubilisation (799 mu g/ml) followed by VM-8 (372 mu g/ml). All the strains except strain VM-8 were HCN producers. Among these three strains, VM-2 and VM-15 showed strong HCN production. These isolates were identified as Rhizobium sp. strain VM-2 (KJ 704783), Brady rhizobium sp. strain VM-8 (KJ 704784), Brady rhizobium sp. strain VM-9 (KJ 704785) and Achromobacter sp. strain VM-15 (KJ501696) after 16S rRNA sequencing. The pot culture experiment showed that VM-8, VM-9 and VM-15 inoculated plants had good results both in inoculated sterilised and inoculated unsterilised soils than the plants grown in sterilised uninoculated soils and control soils. The VM-2 strain showed moderate results under plant inoculation test. This study suggests that these four native rhizobial strains of PGP can be used as bio fertilisers as well as a bio control agent for enhancing the yield of blackgram in rice fallows.

Pd-Catalyzed Ortho-Directed C-H Glycosylation of Arenes Using N-linked Bidentate Auxiliaries

Main observation and conclusion A set of Pd-catalyzed ortho-directed C-H glycosylation reactions with glycosyl chloride donors using various N-linked bidentate auxiliaries has been developed for synthesis of C-aryl glycosides.
