A novel synthesis of N-hydroxy-3-aroylindoles and 3-aroylindoles

A straightforward indole synthesis via annulation of C-nitrosoaromatics with conjugated terminal alkynones was realised achieving a simple, highly regioselective, atom- and step economical access to 3-aroylindoles in moderate to good yields. Further functionalizations of indole scaffolds were investigated and an easy way to JWH-018, a synthetic cannabinoid, was achieved.

Organophosphorus-catalyzed relay oxidation of H-Bpin: electrophilic C-H borylation of heteroarenes

A nontrigonal phosphorus triamide (1, P{N[o-NMe-C6H4](2)}) is shown to catalyze C-H borylation of electron-rich heteroarenes with pinacolborane (HBpin) in the presence of a mild chloroalkane reagent. C-H borylation proceeds for a range of electron-rich heterocycles including pyrroles, indoles, and thiophenes of varied substitution. Mechanistic studies implicate an initial P-N cooperative activation of HBpin by 1 to give P-hydrido diazaphospholene 2, which is diverted by Atherton-Todd oxidation with chloroalkane to generate P-chloro diazaphospholene 3. DFT calculations suggest subsequent oxidation of pinacolborane by 3 generates chloropinacolborane (ClBpin) as a transient electrophilic borylating species, consistent with observed substituent effects and regiochemical outcomes. These results illustrate the targeted diversion of established reaction pathways in organophosphorus catalysis to enable a new mode of main group-catalyzed C-H borylation.

Induction of adventitious roots from leaf explants of Morinda coreia Buch. and ham. : an important dye yielding plant

The present communication reports, induction of adventitious roots (AR) from the in vitro raised leaves of Morinda coreia as affected by auxins and their varying concentrations. The roots of this plant possess anthraquinone, a preferable natural dye, explored well in pharmaceuticals. The AR from the leaves were induced under light and dark conditions within 5 weeks on half-strength Murashige and Shook’s (MS) medium. Among the various auxins and their concentrations tested, half-strength MS medium augmented with indole-3 butyric acid (IBA) at 4.0 mg/L was recorded most favorable in induction of AR (0.7997 gm fresh weight and 0.0698 gm dry weight) with negligible callus under dark conditions. The present study aimed to analyze the combined effect of light/dark and auxins on the induction of AR from the in vitro raised leaves of M. coreia. The protocol can be used for large scale proliferation of roots and enhanced production of dye (anthraquinones).

Nanohybrid of ZnO-RGO as Heterogeneous Green Catalyst for the Synthesis of Medicinally Significant Indole Alkaloids and Their Derivatives

Nanohybrid of ZnO-RGO has been developed and employed as heterogeneous catalyst for the synthesis of medicinally significant organic scaffolds. In this work, the nanohybrid catalyst has been used for the one-pot synthesis of various indole alkaloids and their derivatives in good yields. Several molecules with different substitutions on heterocyclic ring have been synthesized to demonstrate the substrate scope and wide applicability of the catalyst. Indoles with both electron donating and electron withdrawing groups were found to be equally compatible and resulted in good yields. In addition, all the reactions have been performed in green reaction medium with ethanol and water as solvent and the absence of byproducts formed in the reaction makes the strategy Green and sustainable. Furthermore, the nanohybrid catalyst could be recycled multiple times without any significant loss in activity.

Regioselective C3-Phosphonation of Free Indoles via Transition-Metal-Free Radical/Hydrolysis Cascade

The selectivity is of great importance for the preparation of molecules in organic chemistry. Herein, a novel method to enable the highly regioselective C3-phosphonation of free indoles has been developed. This transformation involves a radical and a hydrolysis procedure, and tolerates a range of functional groups, which gives an efficient route toward the 1H-indol-3 – ylphosphonic acid monoesters in one step.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 78415-72-2 is helpful to your research. Category: indole-building-block.

Hydrogen sulfide mitigates cadmium induced toxicity in Brassica rapa by modulating physiochemical attributes, osmolyte metabolism and antioxidative machinery

Hydrogen sulfide (H2S) is helpful for maintaining plant growth under abiotic stresses. The current study elucidated the physiological and biochemical strategies by which sodium hydrosulfide (NaHS), a donor of H2S, alleviated cadmium (Cd) toxicity in Brassica rapa. B. rapa plants growing under 50 mgkg(-1) Cd stress showed reduced leaf relative water contents (LRWC), photosynthetic pigments, total soluble proteins, minerals uptake, antioxidants and growth. Furthermore, enhanced accumulation of Cd contents caused augmentation in levels of electrolyte leakage (EL) and methylglyoxal (MG). Nevertheless, improved physiochemical parameters in B. rapa seedlings obtained from seeds primed with 1.5 mM NaHS resulted better phenotype, growth and biomass production in Cd stressed plants. Protective stimulus of H2S regulated minerals and Cd homeostasis besides increased activity of antioxidants which decreased level of reactive oxygen species (ROS), EL, malondialdehyde (MDA) and MG in Cd regimes. Furthermore, H2S treated seedlings exhibited reduction in Cd content and revealed an active participation in the indole acetic acid (IAA) mediated pathway during stress. The findings of current study propose that H2S yimproved stress tolerance and mitigated Cd stress in B. rapa by modulating growth biomarkers and antioxidative system. (C) 2020 Elsevier Ltd.

Hormonal responses associated with acclimation to freezing stress in Lolium perenne

Complex phytohormonal analyses revealed hormone changes underlying the freezing response of perennial ryegrass (Lolium perenne L.). Comparisons among sensitive (code of accession 1/61), highly tolerant (5/101) and semi-tolerant (6/104; sensitive without acclimation, but tolerant after acclimation) genotypes allowed identification of changes associated with freezing tolerance. The main response to freezing stress (-7 degrees C for four days) was a significant elevation of abscisic acid (ABA) in all tissues of all genotypes, supported by elevation of jasmonic acid (JA) in leaves, and of salicylic acid (SA) in crowns and roots. Jasmonate-isoleucine increase was observed in roots of the tolerant genotype. The auxin (indole-3-acetic acid) levels showed relatively minor changes, while cytokinins exhibited up-regulation in crowns of sensitive genotypes. Tolerant genotypes exhibited decreased levels of highly active cytokinin trans-zeatin compensated by elevated low-active cis-zeatin, involved in stress responses. Cold acclimation (3 degrees C for seven days) applied prior frost treatment was associated with stimulation of plant defences, especially expression of ice recrystallisation inhibition protein LpIRI3. Acclimation diminished the impact of subsequent freezing treatment as indicated by lower up-regulation of stress hormones ABA, JA and SA in all tested tissues (with the exception of SA in crowns and roots of sensitive genotype) and upregulation of active cytokinins in tolerant and semi-tolerant genotypes, especially in crowns and roots.
