Alkanethiol-Mediated Cyclization of o-Alkynylisocyanobenzenes: Synthesis of Bis-Thiolated Indole Derivatives

Reactions of o-alkynylisocyanobenzenes with a variety of alkanethiols (Alk-SH) provide the corresponding bis-thiolated indole derivatives. The advantages of the reaction include metal-free, room-temperature, mild reaction conditions and broad functional group compatibility. The reaction proceeds via nucleophilic addition of an alkanethiol to an isonitrile moiety, 5-exo cyclization, followed by nucleophilic addition of an alkanethiol to a 3-alkylidene indole intermediate. Density functional calculations on the electronic structures and relative free energies of 5-exo and 6-endo cyclization pathways support that the 5-exo cyclization is preferable.

Multicomponent Ugi Reaction of Indole-N-carboxylic Acids: Expeditious Access to Indole Carboxamide Amino Amides

A novel multicomponent Ugi-type reaction for the synthesis of indole carboxamide amino amides from aldehydes, amines, isocyanides, and indole-N-carboxylic acids, which were simply prepared from indoles and CO2, is described. This method provides an expeditious and practical access to indole tethered peptide units, along with the achievement of remarkable structural diversity and brevity. Gram-scale reaction was conducted to demonstrate the scalability, and the products could be transformed to new indole derivatives.

EFFECTS OF ZINC ON INDOLE CARBOXYLIC ACID AND INDOLE ACETIC ACIDS CONTENTS IN RADISH SHOOT

Radish (Raphanus sativus L.) was grown for several experiments in a glasshouse with and without zinc (Zn) in the nutrient solution. Lack of zinc resulted in stunted growth and reduced leaf of radish shoots. Two-dimensional thin layer chromatography (TLC) and gas chromatography-mass spectrometry (GC-MS) analysis revealed the presence of indole carboxylic acid (ICA) (ester + free) and IAA (ester + free) in Zn-deficient radish shoots. Alkali-labile (1M NaOH) ICA and IAA in Zn deficient radish shoots were estimated with the use of GC. The content of ICA in Zn deficient radish shoots was higher than that of control radish shoots. These results suggest that ICA (ester + free) was accumulated in Zn-deficient radish shoots. But the content of IAA (ester + free) in Zn-deficient radish shoots was almost the same as that of control radish shoots. These results suggest that zinc nutrition did not affect the level of IAA in radish shoots.

Metal-Catalyzed Synthesis of Substituted Indoles

Indoles are important structural motifs that are commonly found in a diverse array of natural products, pharmaceuticals, and other functional molecules. Consequently, the development of new, more efficient synthetic methods for the construction of substituted indoles continues to be of great importance and considerable interest. Over the past few decades, metal-catalyzed C-C/C-N bond-forming reactions have emerged as a powerful synthetic strategy for heterocyclic synthesis. In this review, we have provided a brief overview of recent advances in the metal-catalyzed synthesis of substituted indoles through the construction of the pyrrole nucleus of indoles, involving the formation of multiple C-C/C-N bonds.

The microbial consortium of indigenous rhizobacteria improving plant health, yield and nutrient content in wheat (Triticum aestivum)

Aim of the present study was to develop effective indigenous plant growth promoting (PGP) rhizobacteria consortia for enhanced plant growth attributes and nutrient acquisition by wheat crop under greenhouse and field conditions. Six efficient isolates, screened out of 120 isolates from rhizosphere soil based on their biochemical characterization and PGP attributes like indole-3-acetic acid (IAA), hydrogen cyanide (HCN), siderophore production, P-solubilization and N-fixation possessed most of the characters. Out of six isolates, three efficient isolates selected on the basis of effective PGP activities and molecularly characterized of 16S rDNA gene. Three isolated efficient PGPR strains along with a collected strain Pseudomonas aeruginosa were selected for preparing different bioformulation for enhancing plant growth and yield of wheat under greenhouse and field conditions. Tetra combination comprising Bacillus megaterium + Arthrobacter chlorophenolicus + Enterobacter sp. + P. aeruginosa showed significant increase in plant height (24.56% and 47.06%), grain yield (75.80% and 40.09%) and straw yield (76.55% and 42.63%) followed by two tri-inoculation B. megaterium + A. chlorophenolicus + P. aeruginosa and A. chlorophenolicus + Enterobacter spp. + P. aeruginosa as compared to the control under the greenhouse and field experiments, respectively. Similarly, tetra- and tri-inoculations resulted in significantly higher test weight and nutrients acquisition by wheat over the control. Therefore, tetra-inoculation of B. megaterium + A. chlorophenolicus + nterobacter spp. + P. aeruginosa strains can be used as an efficient PGPR consortium for enhanced wheat production.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 648450-29-7. Name: AS-605240.

Collective Total Synthesis of Aspidofractinine Alkaloids through the Development of a Bischler-Napieralski/Semipinacol Rearrangement Reaction

A tandem Bischler-Napieralski/semipinacol rearrangement reaction has been developed for the purpose of assembling a bis(spirocyclic) indole framework, a privileged structural unit of aspidofractinine-type monoterpenoid indole alkaloids, and was used in combination with a subsequent Mannich reaction to expeditiously construct the central bridged bicyclo[2.2.1]heptane ring system of these molecules with contiguous quaternary centers.
