A new method for generation of non-stabilized alpha-amino-substituted carbanions by the reaction of magnesium carbenoids with N-lithio arylamines: their reactivity and a new synthesis of alpha-amino acid derivatives

Magnesium carbenoids were generated from aryl 1-chloroalkyl sulfoxides with i-PrMgCl in THF at low temperature in quantitative yields. The magnesium carbenoids were found to be reactive with N-lithio alkylamines to afford an olefin, which was derived from dimerization of the magnesium carbenoid, in moderate yield. On the other hand, reaction of the magnesium carbenoids with N-substituted N-lithio arylamines gave non-stabilized alpha-amino-substituted carbanions in good yields. Reactivity of the alpha-amino-substituted carbanions with some electrophiles was investigated and it was found that ethyl chloroformate reacted to give alpha-amino acid derivatives in good yields. As a whole, a new method for one-pot, three-component combined synthesis of alpha-amino acid derivatives from aryl 1-chloroalkyl sulfoxides was realized.

Palladium-catalysed direct arylation of heteroaromatics using unprotected iodoanilines with inhibition of the amination reaction

The palladium-catalysed direct arylation of heteroaromatics with unprotected iodoanilines proceeds in moderate to high yields using only 1 mol% Pd(OAc)2 as the catalyst and potassium acetate as the base. No amination reaction was observed under these conditions. A wide variety of heteroarenes have been successfully employed. Georg Thieme Verlag Stuttgart New York.

Sulfonamide Synthesis through Electrochemical Oxidative Coupling of Amines and Thiols

Sulfonamides are key motifs in pharmaceuticals and agrochemicals, spurring the continuous development of novel and efficient synthetic methods to access these functional groups. Herein, we report an environmentally benign electrochemical method which enables the oxidative coupling between thiols and amines, two readily available and inexpensive commodity chemicals. The transformation is completely driven by electricity, does not require any sacrificial reagent or additional catalysts and can be carried out in only 5 min. Hydrogen is formed as a benign byproduct at the counter electrode. Owing to the mild reaction conditions, the reaction displays a broad substrate scope and functional group compatibility.

Water promoted one-pot three-step synthesis of novel n-saccharin isoxa-zolines/isoxazoles using KI/oxone under ultrasonic activation

A green and efficient regioselective protocol was developed for the preparation of novel isoxazolines and isoxazoles of N-saccharin derivatives via the water-promoted cycloaddition reaction of nitrile oxides with alkenes and alkynes. It is noteworthy that KI/Oxone/water-promoted one-pot three-component reactions of aldehyde, hydroxylamine hydrochloride, and alkene or alkyne were observed to be very satisfactory. The synthesis of all adducts (4a-j/5a-j) has been carried out by this method with high to excellent yields (70-95%) at 25C within 30 min, using ultrasonic probe. All the new compounds were thoroughly characterized by spectroscopic techniques and also 5b, 5c and 5f were structurally identified by single-crystal X-ray diffraction methods. X-ray crystallography structure analysis clearly supported the regioselectivity of the cycloaddition reaction.

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.Application In Synthesis of Isoxazole, you can also check out more blogs about288-14-2

Synthesis and characterization of Cu(I) and Zn(II) complexes with new sulfur-bearing isoxazole- or pyrazole-based ligands

The synthesis of the new ligands 6-(5-methyl-1,2-oxazol-3-yl)-2,3-dihydro-5H-[1,4] dithiino[2,3-c]pyrrole-5,7(6H)-dione (isox?) and 6-(3-methyl-1H-pyrazol-5-yl)-2,3-dihydro-5H-[1,4]dithiino[2,3-c]pyrrole-5,7(6H)-dione (pyraz?) and their coordination chemistry toward Cu(I) and Zn(II), was studied. The ligands and their complexes were characterized using a combination of either multinuclear NMR (1H and 13C{1H}), HRMS, FTIR or Uv-Vis spectroscopy. The solid state structures of ligand isox? and complexes [Cu(pyraz?)2]OTf and [Zn(OOCCF3)2(pyraz?)2] were determined. Interestingly, isox? presents a yellow luminescence in its free form. Additionally, the ability of isox? to coordinate as an N-O bidentate ligand or as an N-S bridge between two copper centers, forming a coordination polymer, is studied. The solid state structure of this Cu(I)-isox? 1D coordination polymer is also reported.

Triclosan and its derivatives as antimycobacterial active agents

Tuberculosis (TB) represents one of the leading causes of morbidity and mortality worldwide. Development of new potential drugs is essential because of the existence of latent TB and expansion of drug-resistant TB forms (multidrug-resistant and extensively drug-resistant tuberculosis). Triclosan is a widely used broad-spectrum biocidal agent. It has been shown to inhibit InhA, an essential enoyl acyl carrier protein reductase, resulting in the lysis of Mycobacterium tuberculosis. Triclosan can be considered as a promising compound for the inhibition of InhA and suppression of mycobacterial growth, because this polychlorinated molecule doesn’t require any activation and it is able to affect the function of InhA directly. This approach enables to circumvent resistance to isoniazid. The aim of this review is to describe current knowledge about triclosan and its analogues as potential antimycobacterial agents.

A thio-staudinger reaction: Thermolysis of a vinyl azide in the presence of t-butyl mercaptan

The thermal decomposition of E-3-azido-3-hexene-2,5-dione (1) in protic media gave rise to several novel reactions of the azide 1 including adducts derived from keteneimine 11. Reaction with t-butyl mercaptan yielded two products, keteneimine-derived mercaptan addition product 20 and a sulfenimine 6. Trapping of a vinyl nitrene intermediate or a thio-Staudinger reaction was considered as a possible mechanism for the formation of sulfenimine 6. The absence of the vinyl nitrene addition products 3 and 5 when the thermal decomposition was conducted in either methanol or t-butylamine suggests a thio-Staudinger reaction is operative.
