Decarboxylative Csp3 -N Bond Formation by Electrochemical Oxidation of Amino Acids

Decarboxylative Csp3-N coupling reactions have been developed through electrochemical oxidation of amino acids. The reaction proceeds via anodic oxidative decarboxylation of carboxylic acids to form stabilized carbocations, which are trapped by azoles or amides to construct C-N bonds. This method avoids the preactivation of carboxylic acids and the use of expensive transition-metals and external chemical oxidants.

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 497-25-6 is helpful to your research. Application of 497-25-6

Cyclic hydroxamates, especially multiply substituted [1,2]oxazinan-3-ones

Routes to putative N-acyl-D-ala-D-ala surrogates, beginning with the conversion of 4-, 5-, and 6-membered lactones into 5-, 6-, and 7-membered cyclic hydroxamates, are reported. The key step of the synthesis is trimethylaluminium-promoted cyclization of an omega-aminooxyester. The 7-membered cyclic hydroxamate crystallizes in a chair conformation. Extension of the reaction sequence to homoserine or homoserine lactone leads to cyclocanaline and N-acylated cyclocanalines. The 4-phenylacetamido derivative of cyclocanaline crystallizes in a boat conformation. The attachment of a 2-carboxypropyl substituent to the ring nitrogen of a 4-acylaminocyclocanaline has been effected, prior to cyclization, by coupling of the acyclic aminooxyester precursor to the triflate of benzyl lactate or, after cyclization, by coupling to tert-butyl alpha-bromopropionate in the presence of potassium fluoride – alumina, followed by removal of the protecting group in each case. A six-membered homolog of the antibiotic lactivicin has been synthesized by the reaction of 4-phenylacetamidocyclocanaline with benzyl 2-oxoglutarate in the presence of carbodiimide, followed by hydrogenolysis. Starting with methyl 2,4-dibromo-2,4-dideoxy-L-erythronate, which is available in two steps from L-ascorbic acid, these reaction sequences have been applied to the stereospecific synthesis of a D-alanine derivative whose nitrogen atom is enclosed within a 3,4-disubstituted [1,2]oxazinan-3-one.

Cobalt-Copper Catalyzed C(sp2) ? N Cross Coupling of Amides or Nitrogenated Heterocycles with Styrenyl or Aryl Halides

An efficient C(sp2) ? N cross coupling of cyclic and acyclic amides with styrenyl/aryl/heteroaryl halides catalyzed by cobalt acetylacetonate in combination with copper(I) iodide, has been achieved. A library of diversely substituted cyclic and acyclic enamides have been obtained in high yields by this procedure. The reaction is stereoselective producing (E)?enamides from trans-styrenyl halides and (Z)- products from cis-halides. This procedure has been successfully employed for the coupling of other N-heterocycles such as pyrazole, imidazole and triazole with aryl/styrenyl/heteroaryl halides to produce the corresponding N-coupled products. A probable mechanism has been suggested.

Electrolytic partial fluorination of organic compounds. Part 78: Regioselective anodic fluorination of 2-oxazolidinones

Various 2-oxazolidinones were galvanostatically electrooxidized in the presence of various fluoride salts. It was found that a fluorine atom was introduced to the alpha-position of the nitrogen atom of N-acyl- and N-alkoxycarbonyl-2-oxazolidinones to provide the corresponding alpha-fluorinated products in moderate to good yields. In the case of N-phenoxycarbonyl derivative, fluorination took place on the phenyl group selectively.

The role of oxazolidine derivatives in the treatment of infectious and chronic diseases

Background: Despite being known for their antibacterial activity, the oxazolidines are molecules with wide pharmacological action and may act as anticonvulsants, anti-inflammatory and antineoplasic agents. However, such activities have been poorly explored and only two oxazolidinic derivatives hit the market until now. Therefore, this review covers the main biological activities of oxazolidines, indicating which of the classes and substituents have the best biological results as well as the synthesis methodology used to obtain them. Methods: The search for bibliographic data was made using a question focused on the oxazolidine structure and their respective activities, besides using inclusion/exclusion criteria clearly defined. The selected papers were subjected to qualitative content analysis methodology to be used in this review. Results: The oxazolidines remain excellent candidates for antibacterial, presenting three compounds in clinical testing phase (Radezolide, Cadezolide and Sutezolide), besides being a good candidate as antitubercular agents. Other less explored activities have niches with a great therapeutic potential such as the oxazolidines acting on 5-HT receptors (anticonvulsant) and Zolmitriptan (anti-migraine), and also mefloquine-oxazolidine derivatives which may act as antineoplasic and antitubercular agents. Conclusion: This review summarizes the versatility and great therapeutic potential that oxazolidines can offer, reinforcing the need for further studies and investments for this class of molecules.

Simultaneous quantification of haemoglobin adducts of ethylene oxide, propylene oxide, acrylonitrile, acrylamide and glycidamide in human blood by isotope-dilution GC/NCI-MS/MS

Haemoglobin adducts are highly valuable biomarkers of cumulative exposure to carcinogenic substances. We have developed and applied an analytical method for the simultaneous quantification of five haemoglobin adducts of important occupational and environmental carcinogens. The N-terminal adducts were determined with gas chromatography as pentafluorophenylthiohydantoine derivatives according to the modified Edman-procedure and subsequent acetonization of the glycidamide adduct N-(R,. S)-2-hydroxy-2-carbamoylethylvaline (GAVal). The use of self-synthesized labelled internal standards in combination with tandem mass spectrometry using negative chemical ionisation guarantees both high accuracy and sensitivity of our determination. The limit of detection for N-2-hydroxyethylvaline (HEVal), N-(R,. S)-2-hydroxypropylvaline (HPVal), N-2-carbamoylethylvaline (AAVal) and N-(R,. S)-2-hydroxy-2-carbamoylethylvaline (GAVal) was 2 pmol/g globin, for N-2-cyanoethylvaline (CEVal) it was determined as 0.5 pmol/g globin, which was sufficient to determine the background levels of these adducts in the non-smoking general population. The between-day-precision for all analytes using a human blood sample as quality control material ranged from 4.7 to 12.3%. We investigated blood samples of a small group (n= 104) of non-smoking persons of the general population for the background levels of these haemoglobin adducts. The median values for HEVal, HPVal, CEVal, AAVal and GAVal in a group of 92 non-smoking persons were 18.1, 4.1, <0.5, 29.9 and 35.2 pmol/g globin, respectively. The adduct levels in 12 persons reporting exposure to passive smoke at home were similar for most adducts with median values of 17.2, 4.1, 1.0, 24.9 and 29.7 pmol/g globin for HEVal, HPVal, CEVal, AAVal and GAVal, respectively. Our results point to an elevated uptake of acrylonitrile caused by passive smoking as indicated by higher levels of the corresponding haemoglobin adduct CEVal. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.
