Heterocyclic hybrid frameworks represent a burgeoning domain within the realms of drug discovery and medicinal chemistry, attracting considerable attention in recent years. Thiazole pharmacophore fragments, inherent natural products such as peptide alkaloids, metabolites, cyclopeptides, have demonstrated broad spectrum pharmacological potentials. Given their profound biological significance, plethora thiazole-based hybrids been synthesized through conjugation thiazole moieties with bioactive...
Thiazolidine-2, 4-diones (TZDs) have become a pharmacologically important class of heterocyclic compounds since their introduction in the form glitazones into clinical use for treatment type 2 diabetes. TZDs lower plasma glucose levels by acting as ligands gamma peroxisome proliferators-activated receptors. In addition, this possesses various other biological activities such antihyperglycemic, antimicrobial, anti-inflammatory, anticonvulsant, insecticidal, etc. are also known lowering blood...
Fused heterocyclic 1,2,4-triazoles have acquired much importance because of their interesting biological properties. Although a number methods been reported in the literature which includes oxidation with phosphorus oxychloride, lead tetraacetate, bromine, etc., hypervalent iodine reagents emerged as choice for various synthetically useful transformations due to low toxicity, ready availability and ease handling. A series new...
Abstract This review outlines the progress over recent years in reactions involving combined approach of hypervalent iodine reagents and transition metals such as palladium, nickel, iridium, gold, rhodium, copper, iron, ruthenium, platinum, silver, zinc, rhenium cobalt. enables organic transformations complimentary to traditional manifolds. Hypervalent play a preeminent role chemistry due their versatile reactivity, heteroatom ligands mild reaction conditions. These combination metal...
Abstract Several reactions mended by hypervalent iodine reagents have been developed in aqueous media recently. The evolution of using medium is one the most vital fields organic synthesis to achieve requirements green chemistry. Hypervalent potential replace toxic metals numerous chemical viz . oxidation reactions, coupling α‐ functionaliztion cyclization and halogenations etc due their stability, high selectivity, easy simple experimentation, less nature. In a reaction solvents are...
A series of new symmetrical 3,6‐ bis (aryl) ([1,2,4]triazolo)[3,4‐a:4′,3′‐c]phthalazines 9a‐l has been conveniently synthesized by oxidative cyclization 1,4‐ (substituted benzalhydrazino)phthalazines 8a‐l promoted iodobenzene diacetate under mild conditions (12 examples, up to 93% yield). All the 12 compounds were tested in vitro for their antibacterial activity against two Gram‐positive bacteria, namely, Staphylococcus aureus , Bacillus subtilis and Gram‐negative Escherichia coli...
The synthesis of a series 21 novel 3‐alkyl/aryl‐7/9‐methyl‐10,10a‐dihydroindeno[1,2‐e][1,2,4]triazolo[3,4‐b][1,3,4]thiadiazines ( 4 ) has been achieved by the cyclocondensation between 4/6‐methyl‐2‐tosyloxy‐1‐indanones 2 and 3‐alkyl/aryl‐4‐amino‐5‐mercapto‐1,2,4‐s‐triazoles 3 ). 4/6‐Methyl‐2‐tosyloxy‐1‐indanones were readily accessible through hypervalent iodine oxidation 4/6‐methyl‐1‐indanones using [(hydroxy)tosyloxyiodo]benzene (HTIB, Koser's reagent) in acetonitrile.
In this paper we fuzzify the bilinear colour interpolation and non-linear differential correlative techniques of demosaicking, using edge strength map mosaic image. doing so ensure that edges have less participation in thereby minimizing error. The result is faster more accurate demosaicking algorithms with application to high resolution images. overall improvement quite significant when it comes definition/high images containing a lot detail or as proved by extensive experimental results on...
Abstract: An efficient approach for the tosyloxyl group transfer in several N-arylbenzamides has been achieved using HTIB (Koser’s reagent) under mild reaction conditions. Its simplicity, efficiency, and reduced reliance on hazardous reagents make it an attractive choice chemists seeking sustainable alternatives. The proposed methodology offered single-step para-selective tosyloxylation, ensuring prevention of synthesis mixtures ortho meta-isomers. corresponding products were obtained with...
