The synthesis of 3,3-dimethylmorpholine-2,5-diones 4a was achieved conveniently via the ‘direct amide cyclization’ of the linear precursors of type 3, which were prepared by coupling of 2,2-dimethyl-2H-azirin-3-amines 2 with 2-hydroxyalkanoic acids 1. Thionation of 4a with Lawesson’s reagent yielded the corresponding 5-thioxomorpholin-2-ones 10 and morpholine-2,5-dithiones 11, respectively, depending on the reaction conditions. The structures of 3aa, 4aa, 10a, and 11a were established by X-ray crystallography. All attempts to prepare S-containing morpholine-2,5-dione analogs or thiomorpholine-2,5-diones by cyclization of corresponding S-containing precursors were unsuccessful and led to various other products. The structures of some of them have also been established by X-ray crystallography.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.you can check my other blog about 100-13-0, you can contact me at any time and look forward to more communication.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process., Application In Synthesis of 4,5-Dimethylbenzene-1,2-diamine, 3171-45-7, Name is 4,5-Dimethylbenzene-1,2-diamine, molecular formula is C8H12N2, belongs to thiomorpholine compound. In a document, author is Dellinger, Douglas J., introduce the new discover.

An improved method for the chemical synthesis of RNA was developed utilizing a streamlined method for the preparation of phosphoramidite monomers and a single-step deprotection of the resulting oligoribo-nucleotide product using 1,2-diamines under anhydrous conditions. The process is compatible with most standard heterobase protection and employs a 2′-O-(1,1-dioxo-1 lambda(6)-thiomorpholine-4-carbothioate) as a unique 2′-hydroxyl protective group. Using this approach, it was demonstrated that the chemical synthesis of RNA can be as simple and robust as the chemical synthesis of DNA.

Thrombin is a serine protease that plays a key role in blood clotting. Pyrrolidine 1 is a potent thrombin inhibitor discovered at Merck several years ago. Seven analogs (2-8) of 1 in which the pyrrolidine core was replaced with various heterocycles were prepared and evaluated for activity against thrombin, clotting factors VIIa, IXa, Xa, and XIIa, and trypsin. The thiomorpholine analog 6 was the most active, essentially matching the thrombin inhibitory activity of 1 with slightly improved selectivity over trypsin. (C) 2014 Elsevier Ltd.

Four new cobalt(III) complexes of the general formula [Co(Rdtc)cyclam](ClO4)(2), where cyclam and Rdtc(-) refer to 1,4,8,11-tetraazacyclotetradecane and 2-, 3-, 4-methylpiperidine (2-, 3-, 4-wMeepipdtc(-)) or 4-thiomorpholine (Timdtc(-)) dithiocarbamates, respectively, have been prepared. Elemental and thermal analyses, VIS, IR and H-1 and C-13 NMR spectroscopy have been used to characterized them. In the complexes, cobalt is hexa-coordinated in an octahedral geometry of a folded macrocyclic ligand and dithiocarbamates are bound as bidentates. As regards to the influence of the position of the methyl group on the piperidine ring, the nu(C – N) and nu(C – S) values increase in the order 2-Mepipdtc(-) < 3-Mepipdtc(-) < 4-Mepipdtc(-). Furthermore, the position of the methyl substituent also influences the thermal stability of the complexes and the order of stability decreases in the opposite order.

New research progress on 7311-34-4 in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 7311-34-4, Name is 3,5-Dimethoxybenzaldehyde, molecular formurla is C9H10O3. In a document, author is Tanini, Damiano, introducing its new discovery. Product Details of 7311-34-4.

Seleno-Michael additions of stable functionalised primary alkyl selenols to activated alkenes and alkynes are described. In the presence of Al2O3, -hydroxy-, -amino-, and -mercapto selenols react smoothly with electron-poor alkenes and alkynes to afford the corresponding unsymmetrical functionalised dialkyl- and alkyl-vinyl-selenides in good yield. The very mild conditions allow a broad range of selenols and Michael acceptors to be converted into the corresponding synthetically valuable seleno-Michael adducts, demonstrating high selectivity and excellent functional group tolerance. Hydroxy- and mercapto-substituted vinyl selenides were efficiently employed for the synthesis of functionalised 1,3-oxaselenolanes, 1,3-thiaselenolanes, and 1,4-thiaselenanes through intramolecular oxa- and thia-Michael additions. Furthermore, a NaH-promoted lactonization enables the synthesis of variously substituted 2-oxo-1,4-oxaselenanes from hydroxy-vinyl-selenides. Evaluation of thiol peroxidase-like properties of novel functionalised organoselenides demonstrated that they possess a remarkable catalytic antioxidant activity.
