Avvadukkam, J; Badiadka, N; Kunhanna, SB; Kumar, MS in [Avvadukkam, Jayashree; Badiadka, Narayana] Mangalore Univ, Dept Studies Chem, Mangalore 574199, India; [Kunhanna, Sarojini B.] Mangalore Univ, Dept Ind Chem, Mangalore, India; [Kumar, Madan S.] Univ Mysore, DST PURSE Lab, Vijnana Bhavan, Mysuru, India published A facile synthesis of pyrano[2,3-d:6,5-d ‘]dipyrimidines via microwave-assisted multicomponent reactions catalyzed by beta-cyclodextrin in 2021.0, Cited 73.0. Product Details of 93-02-7. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7.

A facile three-component reaction of aromatic aldehyde, 2,2-dimethyl-1,3-dioxane-4,6-dione, and 6-amino-1,3-dimethyluracil was developed for the first time using beta-cyclodextrin (beta-CD) as a macrocyclic host for aldehyde and an efficient catalyst that leads to a batch of novel pyrano[2,3-d:6,5-d ‘]dipyrimidines (4a-k). The synthesis was accomplished with the aid of microwave irradiations in solvent-free conditions. The product obtained was in contrast to the previous report in which a similar reaction resulted in a mixture of benzylidenepyrimidine and bisaminopyrimidine analogs in the presence of triethylbenzylammonium chloride in an aqueous medium. The formation of the pyrano[2,3-d:6,5-d ‘]dipyrimidines may be in virtue of the property of beta-CD to construct new C-C and C-X (where X = heteroatom) bonds. Reusability of the catalyst up to three runs without any noteworthy change in catalytic activity is one of the main features of the reaction. Other noteworthy features are good to excellent yields, eco-friendly procedure, non-column chromatographic purification, and mild conditions.

A one-step synthesis of acyl phosphoramidates from a variety of functionalized acyl azides has been developed employing trimethylsilyl chloride as an activating agent in a modified Staudinger reaction. The methodology was further adapted to include the in situ generation of the acyl azides from a diverse selection of carboxylic acids and hydrazide starting synthons. The reaction scope was extended to include the synthesis of imidodiphosphates and the natural product Microcin C.

An efficient and simple approach for the direct synthesis of aryl and heteroaryl sulfonic esters was developed using DMS and DES as alkoxysulfonylation reagents. The reaction is operationally simple and scalable. This protocol does not require solvent, expensive catalysts, base, ligand additives or other reagents. A wide range of sulfonic esters were synthesized in moderate to good chemical yields. This method has the advantage of low cost, facile and tolerated a wide range of substrates.

Direct C-S bond coupling is an attractive way to construct aryl sulfur ether, a building block for a variety of biological active molecules. Herein, we disclose an effective model for regioselective thiolation of the aromatic C-H bond by thiol activation instead of arene activation. Strikingly, this method has been applied into anisole derivatives that are not available in the arene activation approach to forge a single thioether isomer with high reactivity.

Safety of 2,6-Difluorobenzoic acid. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Synthesis, structural characterization and antimycobacterial evaluation of several halogenated non-nitro benzothiazinones published in 2021, Reprint Addresses Seidel, RW (corresponding author), Martin Luther Univ Halle Wittenberg, Inst Pharm, Wolfgang Langenbeck Str 4, D-06120 Halle, Saale, Germany.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid.

8-Nitro-1,3-benzothiazin-4-ones (BTZs), with BTZ043 and PBTZ169 as the most advanced compounds, represent a new class of potent antitubercular agents, which irreversibly inhibit decaprenylphosphoryl-beta-d-ribose-2 ‘-epimerase (DprE1), an enzyme crucial for cell wall synthesis in the pathogen Mycobacterium tuberculosis. Synthesis, structural characterization and in vitro testing against Mycobacterium aurum DSM 43999 and M. tuberculosis H(37)Rv of halogenated 2-(4-ethoxycarbonylpiperazin-1-yl)-1,3-benzothiazin-4-ones lacking a nitro group are reported. X-ray crystallography reveals that the structure of the BTZ scaffold can significantly deviate from planarity. In contrast to recent reports, the results of the present study indicate that further investigation of halogenated non-nitro BTZs for antitubercular activity is less than a promising approach.

The coordination of biologically active moieties to the axial positions of Pt(IV) derivatives of Pt(II) anticancer drugs allows the co-delivery and simultaneous activation of two pro-drugs for combination therapy. Pt(IV) complexes with a redox modulator as an axial ligand can kill cancer cells by a mechanism combining DNA platination and generation of oxidative stress. In this study we evaluated the cytotoxicity of Pt(IV) complexes based on the oxaliplatin scaffold and the pro-oxidant indole-3-propionate in cisplatin-sensitive and cisplatin-resistant ovarian cancer cells. A series of five complexes was synthesized and characterized by H-1 and Pt-195 NMR spectroscopy, IR spectroscopy, mass spectrometry and elemental analysis; trans-[Pt(DACH)(ox)(IPA)(OH)] (1), trans-[Pt(DACH)(ox)(IPA)(2)] (2), trans-[Pt(DACH)(ox)(IPA)(bz)] (3), trans-[Pt(DACH)(ox)(IPA)(suc)] (4), and trans-[Pt(DACH)(ox)(IPA)(ac)] (5) (DACH = 1,2-diaminocyclohexane (1R, 2R)-(-), ox = oxalate, IPA = indole 3-propionate, bz = benzoate, suc = succinate and ac = acetate). The complexes were shown to produce cellular reactive oxygen species (ROS) in a time-dependent manner. The most potent ROS producer, complex 1, also elicited the highest cytotoxicity. Complex 1 was shown to form the mono-and bis-adducts [Pt(DACH)(guanosine)( OH)](+) and [Pt(DACH)(guanosine)(2)](2+) in the presence of ascorbic acid, suggesting that on activation the released oxaliplatin will interact with DNA.

Photoexcited electron-hole pairs on a semiconductor surface can engage in redox reactions with two different substrates. Similar to conventional electrosynthesis, the primary redox intermediates afford only separate oxidized and reduced products or, more rarely, combine to one addition product. Here, we report that a stable organic semiconductor material, mesoporous graphitic carbon nitride (mpg-CN), can act as a visible-light photoredox catalyst to orchestrate oxidative and reductive interfacial electron transfers to two different substrates in a two-or three-component system for direct twofold carbon-hydrogen functionalization of arenes and heteroarenes. The mpg-CN catalyst tolerates reactive radicals and strong nucleophiles, is straightforwardly recoverable by simple centrifugation of reaction mixtures, and is reusable for at least four catalytic transformations with conserved activity.

We recently reported a new class of chiral ruthenium catalysts in which two achiral bidentate N-(2-pyridyl)-substituted N-heterocyclic carbene ligands in addition to two labile acetonitriles are coordinated to a central ruthenium and generate a stereogenic metal center which is responsible for the overall chirality (Zheng et al. J. Am. Chem. Soc. 2017, 139, 4322). Here we now report our discovery of related chiral-at-ruthenium catalysts in which normal and abnormal N-heterocyclic carbene (NHC) ligands are present at the same time. The synthesis of racemic complexes, their resolution into individual enantiomers by a chiral auxiliary approach, and a catalytic application are reported. The mixed normal/abnormal NHC complexes display significantly increased turnover numbers and turnover frequencies for a nitrene-mediated enantioselective C(sp(3))-H amination.
