1123-49-5, Name is 3,5-Dimethyl-4-nitroisoxazole, belongs to isoxazole compound, is a common compound. SDS of cas: 1123-49-5In an article, once mentioned the new application about 1123-49-5.

Treatment of cis-[PtCl2(Me2SO)2] with the pyrazole acetoximes p-RC6H4{CN(H)NCCH}CH2C(Me)=NOH (R=OMe, H, F, Cl, CN, NO2), prepared by a cascade reaction from the vinyl isoxazoles p-RC6H4C(H)=C(H){CONCC(NO2)}Me, leads to the complexes [PtCl2(Ar{CN(H)NCCH}CH2C(Me)=NOH)] (71?88 %). The complexes exhibit solid state room temperature phosphorescence with emission maxima in the region of 644?691 nm and biexponential relaxation with tau1? 2 ms and tau2? 0.32 ms. In the platinum compounds, substituents R affect phosphorescence quantum yields, which increase by one order of magnitude on going from electron acceptor (R=NO2; 0.2 %) to electron-donor groups (R=OMe; 2.0 %). Based upon theoretical TD-DFT calculations using the CAM?B3LYP functional, the absorption spectra were attributed to metal-to-ligand charge transfer (1MLCT) and ligand-to-ligand charge transfer (1LLCT) processes. The pyrazole acetoximes and their complexes were characterized by elemental analyses (C, H, N), HRESI-MS, FTIR, 1H NMR (for metal-free species), and CP-MAS TOSS 13C{1H} NMR (for the platinum complexes). In addition, two complexes were studied by single-crystal X-ray diffraction.

In this work, the first application of 3,5-dimethyl-4-nitroisoxazole as a vinylogous pronucleophile in the allylic-allylic alkylation of Morita-Baylis-Hillman (MBH) carbonates is described. The reaction has been realized under nucleophilic catalysis conditions with dimeric cinchona alkaloids, providing excellent enantiocontrol of the process. The usefulness of the products thus obtained has been confirmed in selected chemoselective reactions. The most important one involves the transformation of the isoxazole moiety into a carboxylic acid group, thus opening access to dicarboxylic acid derivatives.

(Chemical equation presented) Nitro versus nitro: 4-Nitro-5- styrylisoxazoles were used as masked alpha,beta-unsaturated carboxylic acids in the titled catalytic asymmetric transformation. The 4-nitroisoxazole core acts as an activator of the conjugated alkene and a latent carboxylate functionality. The reaction proceeded with 5 mol% of a readily prepared phasetransfer catalyst at room temperature with remarkable diastereo- and enantioselectivity (see scheme).
