Structurally diverse copper(II)-carboxylato complexes: Neutral and ionic mononuclear structures and a novel binuclear structure

The copper complexes with the commercial auxin herbicides MCPA, 2,4-D, and 2,4,5-T in the presence of a nitrogen donor heterocyclic ligand, phen or bipyam, were prepared and characterized. The available evidence supports a dimeric structure for the 2,4-D complex in the presence of bipyam while phen leads to monomeric forms. The EPR spectrum of Cu2(2,4-D)4(bipyam)2 at 4 K in the solid state exhibits an axial signal which corresponds to almost isolated S = 1/2 magnetic ions. Magnetic data for the dimer show a weak antiferromagnetic interaction between the two metal ions with J = -0.8 cm-1. The crystal structures of tetrakis[(2,4-dichlorophenoxy)acetato]bis(2,2′-bipyridylamine)dicopper(II), 1, bis(1,10-phenanthroline)[(2,4,5-trichlorophenoxy)acetato]copper(II) chloride, 2, and aqua(1,10-phenanthroline)bis[((2-methyl-4-chlorophenoxyacetato]copper(II), 3, were determined and refined by least-squares methods using three-dimensional MoKalpha data. 1 crystallizes in space group P1, in a cell of dimensions a = 10.813(1) A, b = 12.138(1) A, c = 11.909(1) A, alpha = 86.448(3), beta = 80.127(3), and gamma = 63.982(3), and V = 1383.7(2) A3, with Z = 1.2 crystallizes in space group I2/a, in a cell of dimensions a = 29.958(9) A, b = 11.342(3) A, c = 21.196(7) A, beta = 107.94(1), and V = 6852.2(4) A3, with Z = 8. 3 crystallizes in space group P1, in a cell of dimensions a = 8.7419(8) A, b = 12.512(1) A, c = 14.598(1) A, alpha = 110.737(1), beta = 95-742(2), gamma = 103.286(2), V = 1424.1(2) A3, with Z = 2.

Green’ synthesis of 2-substituted 6-hydroxy-[3H]-pyrimidin-4-ones and 4,6-dichloropyrimidines: Improved strategies and mechanistic study

An improved route to 2-substituted 6-hydroxy-[3H]-pyrimidin-4-ones 4 and to 2-substituted 4,6-dichloropyrimidines 5 is reported. Without using highly toxic reactants, compounds 4 can be prepared conveniently in a one pot synthesis on a one mol scale with average yields up to 80%. 4,6-Dichloropyrimidines 5, which are usually prepared in small quantities, are synthesized with average yields of 80%, using up to 80g of starting material. The mechanism of the chlorination of 4 is investigated computationally for the first time. The results suggest that the chlorination with phosphoryl chloride occurs in an alternating phosphorylation-chlorination manner (pathway 1) which is preferred over a sequence which starts with two phosphorylations. The investigated 4,6-dichloropyrimidines described herein form strong complexes with dichlorophosphoric acid but weak complexes with hydrochloric acid (generated during workup). These latter complexes explain the necessity of using aqueous sodium carbonate during the working up. In order to prevent possible formation of pyrimidinium salts between intermediates or the final dichloropyrimidines and unreacted hydroxypyrimidone, the latter could be deactivated with a strong acid such as dichlorophosphoric acid, thus allowing chlorination but prohibiting salt formation. Because of its general applicability to all nitrogen heterocycle chlorinations with phosphoryl chloride, the proposed route to dichloropyrimidines without solvent or side products, using less toxic reactants, is of general synthetic interest.

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.Recommanded Product: 2H-Pyran-3,5(4H,6H)-dione, you can also check out more blogs about61363-56-2

Inhibition of the Replication of Different Strains of Chikungunya Virus by 3-Aryl-[1,2,3]triazolo[4,5- d] pyrimidin-7(6 H)-ones

The re-emergence of chikungunya virus (CHIKV) is a serious global health threat. CHIKV is an alphavirus that is transmitted to humans by Aedes mosquitoes; therefore, their wide distribution significantly contributes to the globalization of the disease. Unfortunately, no effective antiviral drugs are available. We have identified a series of 3-aryl-[1,2,3]triazolo[4,5-d]pyrimidin-7(6H)-ones as selective inhibitors of CHIKV replication. New series of compounds have now been synthesized with the aim to improve their physicochemical properties and to potentiate the inhibitory activity against different CHIKV strains. Among these newly synthesized compounds modified at position 3 of the aryl ring, tetrahydropyranyl and N-t-butylpiperidine carboxamide derivatives have shown to elicit potent antiviral activity against different clinically relevant CHIKV isolates with 50% effective concentration (EC50) values ranging from 0.30 to 4.5 muM in Vero cells, as well as anti-CHIKV activity in human skin fibroblasts (EC50 = 0.1 muM), a clinically relevant cell system for CHIKV infection.

Use of N,O-dimethylhydroxylamine as an anomeric protecting group in carbohydrate synthesis

The N,O-dimethyloxyamine-N-glycosides are introducedas anomerically protected building blocks for carbohydrate synthesis. These N-glycosides are stable to a variety of protecting group manipulations including acylation, alkylation, silylation, and acetal formation. The alkoxyamine-N-glycosides can be cleaved selectively with N-chlorosuccinimide to give the desired hemiacetals in excellent yield. Furthermore, these Nglycosides are stable to the activation conditions required for glycosylation using thioglycoside and trichloroacetimidate glycosyl donors suggesting N,O-dialkoxyamine-N-glycosides will be useful for complex oligosaccharide synthesis.

Quantitative production of 2-acetamido-2-deoxy-D-glucose from crystalline chitin by bacterial chitinase

Finely powdered alpha- and beta-chitin can be completely hydrolyzed with chitinase (EC 3.2.1.14) and beta-N-acetylhexosaminidase (EC 3.2.1.52) for the production of 2-acetamido-2-deoxy-D-glucose (GlcNAc). Crude chitinase from Burkholderia cepacia TU09 and Bacillus licheniformis SK-1 were used to digest alpha- and beta-chitin powder. Chitinase from B. cepacia TU09 produced GlcNAc in greater than 85% yield from beta- and alpha-chitin within 1 and 7 days, respectively. B. licheniformis SK-1 chitinase completely hydrolyzed beta-chitin within 6 days, giving a final GlcNAc yield of 75%, along with 20% of chitobiose. However, only a 41% yield of GlcNAc was achieved from digesting alpha-chitin with B. licheniformis SK-1 chitinase.
