The nitroso Diels-Alder (NDA) reaction is an attractive strategy for the synthesis of 3,6-dihydro-1,2-oxazines and 1-amino-4-hydroxy-2-ene derivatives. Herein we report the Cu(I)-DTBM-Segphos catalyzed asymmetric intermolecular NDA reaction of variously substituted cyclic 1,3-dienes using highly reactive nitroso compounds derived from pyrimidine and pyridazine derivatives. In most of the cases studied, the cycloadducts were obtained in high yields (up to 99%) with very high regio-, diastereo-, and enantioselectivities (up to regioselectivity > 99:1, d.r. > 99:1, and >99% ee). As an application of this methodology, formal syntheses of conduramine A-1 and narciclasine were accomplished.

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Synthetic Route of 5788-58-9, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 5788-58-9, name is 4,5-Dibromopyridazin-3(2H)-one. In an article，Which mentioned a new discovery about 5788-58-9

High-throughput screening of a small-molecule library identified a 5-triazolo-2-arylpyridazinone as a novel inhibitor of the important glycolytic enzyme 6-phosphofructo-2-kinase/2,6-bisphosphatase 3 (PFKFB3) Such inhibitors are of interest due to PFKFB3’s control of the important glycolytic pathway used by cancer cells to generate ATP A series of analogues was synthesized to study structure-activity relationships key to enzyme inhibition Changes to the triazolo or pyridazinone rings were not favoured, but limited-size substitutions on the aryl ring provided modest increases in potency against the enzyme Selected analogues and literature-described inhibitors were evaluated for their ability to suppress the glycolytic pathway, as detected by a decrease in lactate production, but none of these compounds demonstrated such suppression at non-cytotoxic concentrations

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 5788-58-9Synthetic Route of 5788-58-9

Product Details of 141-30-0, The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

A new hexadentate ligand 3,6-bis[(6-methyl-2-pyridyl)(2-pyridyl)methyl]pyridazine (mbdpdz) was prepared by a condensation reaction of 3,6-dichloropyridazine and (6-methyl-2-pyridyl)(2-pyridyl)methyllithium, and the following binuclear copper(II) complexes were obtained: [Cu2(mbdpdz)Cl4] 1, [Cu2(mbdpdz)Br4] 2, [Cu2(mbdpdz)-Cl2(OH)]Cl 3 and [Cu2(mbdpdz)Br2(OH)]Br 4. The crystal and molecular structures of the two isomorphous complexes 3 and 4 are reported. Both complexes crystallize in the monoclinic system, space group C2/c, with eight formula units per unit cell. Complex 3: a = 28.364(3), b = 13.511(1), c = 16.858(1) A, beta = 109.70(1). Complex 4: a = 28.528(5), b = 13.459(2), c = 17.348(3) A, beta = 109.35(1). The copper centres in the binuclear cation in 3 and 4 have a square-pyramidal geometry, with a bridging hydroxide angle of 115.1(3) and 116.2(5) respectively. The Cu…Cu distance was 3.251(2) A in both binuclear complexes. These hydroxo-bridged complexes were obtained by refluxing acetonitrile-water suspensions of 1 and 2, respectively. Variable-temperature magnetic studies on all complexes indicate the existence of antiferromagnetic exchange phenomena. Extended-Hueckel calculations were performed on complexes 3 and 4 in order to identify the electronic origin of the spin coupling of these molecules.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Synthetic Route of 141-30-0. Introducing a new discovery about 141-30-0, Name is 3,6-Dichloropyridazine

An efficient synthesis of a series of 6-chloro-3-substituted-[1,2,4]triazolo[4,3-b]pyridazines is described via intramolecular oxidative cyclization of various 6-chloropyridazin-3-yl hydrazones with iodobenzene diacetate. The structures of the newly synthesized compounds were assigned on the basis of elemental analysis, IR, NMR (1H and 13C) and mass spectral data. All the thirty three compounds 3a-q and 4b-q synthesized in the present study were evaluated for their in vitro cytotoxic activities against two Acute Lymphoblastic Leukemia (ALL) cell lines named, SB-ALL and NALM-6, and a human breast adenocarcinoma cell lines (MCF-7). The results revealed that triazoles 4 exhibit better cytotoxicity than their hydrazone precursors 3. Among triazoles, compounds 4f, 4j and 4q exhibited potent cytotoxic activity against SB-ALL and NALM-6 with IC50 values in the range of ?1.64?5.66 muM and ?1.14?3.7 muM, respectively, compared with doxorubicin (IC50 = 0.167 muM, SB-ALL). Compounds 4f, 4j and 4q were subjected to apoptosis assay after 48 h treatment and these compounds induced apoptosis of NALM-6 cells via caspase 3/7 activation. Results revealed that compound 4q represents potential promising lead.

An efficient and halogen-free catalytic methodology for the synthesis of beta-amino alcohols from aromatic amines and biomass-derived carbohydrates is demonstrated for the first time. The activation of C5/C6 sugars by a ruthenium catalyst selectively generates the C2 alkylating reagent glycolaldehyde. The transformation involves metal-catalyzed hydrogen borrowing for the reduction of the imine intermediate. A series of arylamines bearing various substituents were successfully transformed into the desired products in good to excellent yields.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons.
