Electrooxidation enables highly regioselective dearomative annulation of indole and benzofuran derivatives

The dearomatization of arenes represents a powerful synthetic methodology to provide three-dimensional chemicals of high added value. Here we report a general and practical protocol for regioselective dearomative annulation of indole and benzofuran derivatives in an electrochemical way. Under undivided electrolytic conditions, a series of highly functionalized five to eight-membered heterocycle-2,3-fused indolines and dihydrobenzofurans, which are typically unattainable under thermal conditions, can be successfully accessed in high yield with excellent regio- and stereo-selectivity. This transformation can also tolerate a wide range of functional groups and achieve good efficiency in large-scale synthesis under oxidant-free conditions. In addition, cyclic voltammetry, electron paramagnetic resonance (EPR) and kinetic studies indicate that the dehydrogenative dearomatization annulations arise from the anodic oxidation of indole into indole radical cation, and this process is the rate-determining step.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 6146-52-7. The above is the message from the blog manager. Quality Control of 5-Nitroindole.

Utilization of Indole-3-acetic acid-Secreting Bacteria in Algal Environment to Increase Biomass Accumulation of Ochromonas and Chlorella

Application of plant hormones is an effective strategy to further improve the accumulation of microalgae biomass. In this study, the IAA (indole-3-acetic acid) production capacity of symbiotic bacteria isolated from the culture system of Ochromonas and Chlorella was detected and compared, with the bacterial community structure revealed. The results demonstrated that Algoriphagus, Porphyrobacter, Roseococcus, and Rhizobium were the dominant bacterial genera both in Ochromonas and Chlorella system, distributed in Proteobacteria and Bacteroidetes. Sixteen of 40 strains classified into 15 genera isolated from the two genera of microalgae could produce IAA, with Agrobacterium and Rhizobium as the main representatives with highest IAA production level (22.53-34.18 mg/L in 30 h). And through determination of changes of chlorophyll content in the co-culture system of microalgae and the supernatant of IAA high-yielding bacteria suspension from medium with or without tryptophan (synthetic precursor of IAA), Rhizobium (C-3) and Agrobacterium (O-16, C-2) were proved to promote the growth of Ochromonas and Chlorella through secreting IAA. The biomass yield of Ochromonas and Chlorella could be respectively increased by 78.98% and 72.73% through the co-culture with Agrobacterium (C-2), by 68.15% and 69.93% for Rhizobium (C-3) and by 80.89% and 65.73% for Agrobacterium (O-16). Moreover, compared with the application of exogenous IAA to improve the microalgae biomass, it is more efficient and economical to construct algae bacteria symbiosis system using IAA secretory bacteria commonly existed in microalgae culture system. In addition, the growth promoting effect of IAA secretory bacteria on microalgae was different among the species of algae.

Magnetically recyclable CuFe2O4 catalyst for efficient synthesis of bis (indolyl)methanes using indoles and alcohols under mild condition

Bis(3-indolyl)methanes (BIM) are highly valuable and appear in the core structure of many natural products and pharmacologically active compounds (anticancer, anti-inflammatory, antiobesity, antimetastatic, antimicrobial, etc.). Herein, we have disclosed an air stable and highly efficient CuFe2O4 heterogeneous catalyst for alkylation of indoles with alcohols to give bis(3-indolyl)methanes in very good yields. The CuFe2O4 catalyst has been found to be magnetically recycled at least five times without losing significant catalytic activity.

Selective Optical Chemosensors of Fe3+ Ions using 1H-Indole-2,3-dione

1H-Indole-2,3-dione has attracted many attentions in the field of organic synthesis due to its easy modification with other organic compounds. On the other hand, 1H-indole-2,3-dione compound could also be used as chemosensor agent because it contains amide and carbonyl functional groups, which are able for binding as well as chelating metal ions. In the present work, we reported that 1H-indole-2,3-dione compound exhibits high sensing capability as well as high selective detection of Fe3+ ions through enhancement of its absorption peak at ultraviolet region. Particularly, a series of 0.5 mM of metal ions (1la+, K+, Ba2+, ca2+, co2+, cu2+,Hgz+mg2+, mn2+, Ni2+, pb2+, zn2+, A u3+, A13+, Fe3+ and La3+) in distilled water was simply mixed with 0.05 mM of 1H-indole-2,3-dione in distilled water. Afterward, their UV-Vis spectral changes were recorded by using UV-Vis spectrophotometer. It was found that 1H-indole-2,3-dione itself gave two main absorption peaks at 242 and 302 nm. When the Fe3+ ions were added, the intensity of both absorption peaks was remarkably increased. From the UV-Vis titration experiment, limit of detection value was found to be 17.8,uM while limit of quantitation was found as 59.3,uM. This finding shows that the 1H-indole-2,3-dione gives a promising platform for fluorescent chemosensor agent for sensing of Fe3+ ion.

A Bioinspired Synthesis of Polyfunctional Indoles

Polyfunctional indoles bearing substituents at C5 and C6 are prevalent in natural products, pharmaceuticals, agrochemicals, and materials. Owing to the remoteness of the C5 and C6 positions, indoles of this family can be difficult to prepare, and often require multistep syntheses. Herein, we describe a concise process that converts simple derivatives of tyrosine into 5,6-difunctionalized indoles by direct oxidation of C-H, N-H, and O-H bonds. Our work draws inspiration from the biosynthetic polymerization of tyrosine to make melanin pigments, but makes an important departure to provide well-defined indole heterocycles.

Unprecedented Reactivity of gamma-Amino Cyclopentenone Enables Diversity-Oriented Access to Functionalized Indoles and Indole-Annulated Ring Structures

Observation of an unexpected, Lewis acid promoted displacement of latent reactive gamma-amino group on cyclopentenone presented unparalleled opportunity for enone functionalization and annulations with indole derivatives, which is developed in the current study. Herein, a vast range of C3/N-indolyl enones and indole alkaloid-like compound were accessed in excellent yields (up to 99 %) and selectivity through a one-pot operation.

Colonization of Vigna radiata by a halotolerant bacterium Kosakonia sacchari improves the ionic balance, stressor metabolites, antioxidant status and yield under NaCl stress

Salinity stress is a major limiting factor that adversely affects the crop productivity. Considering these problems, present investigation was aimed to isolate and characterize a halotolerant PGPR strain to circumvent these problems. Strain MSK1 tolerated exceptionally 1000 mM of NaCl and identified as K. sacchari using 16S rRNA sequence analysis (accession number MG028651). Strain MSK1 was found metabolically active, producing substantial amount of growth regulating substances such as indole-3-acetic acid, ACC deaminase, siderophore, ammonia and hydrogen cyanide which, however, increased with increasing NaCl concentrations. Vigna radiata was used as test crop to evaluate the effect of NaCl as well as remediating potential of halotolerant K. sacchari. Phytotoxicity of salt to V. radiata plants was obvious under both in vitro and in vivo environments and increased in a dose related manner. Among the concentrations, the higher NaCl level (400 mM) exhibited more pronounced detrimental effect and significantly (P <= 0.05) decreased the germination attributes, dry biomass, photosynthetic pigments, symbiotic features and seed yield of V. radiata. However, antioxidant enzymes, proline, MDA, membrane damage, H2O2 content, relative leaf water content (RLWC) and Na+/K+ ion concentrations were increased with increasing NaCl concentrations. Contrarily, following soil inoculation, halotolerant K. sacchari MSK1 alleviated the salinity stress and improved the plant performance and augmented the dry biomass, chlorophyll formation, symbiosis and yield of V. radiate even in salt stressed condition. Besides these, strain MSK1 reduced the level of proline, MDA, H2O2 and antioxidant enzyme activity. Additionally, RLWC, membrane injury and Na+/K+ ions were reduced following the application of K. sacchari. The root colonization efficiency of K. sacchari even under salinity stress was examined by scanning electron microscopy. Conclusively, it can surely be suggested that halotolerant MSK1 strain could inexpensively be explored as best choice for augmenting the V. radiata production under salinity stressed soils. 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 480-18-2, in my other articles.
