Pd(II)-catalyzed enantioselective C-H activation of cyclopropanes

Systematic ligand development has led to the identification of novel mono-N-protected amino acid ligands for Pd(II)-catalyzed enantioselective C-H activation of cyclopropanes. A diverse range of organoboron reagents can be used as coupling partners, and the reaction proceeds under mild conditions. These results provide a new retrosynthetic disconnection for the construction of enantioenriched cis-substituted cyclopropanecarboxylic acids.

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.Safety of 3-Bromo-6-chloropyridazine, you can also check out more blogs about89089-18-9

Oxidative addition of haloheteroarenes to palladium(0): Concerted versus SNAr-type mechanism

The kinetics of the oxidative additions of haloheteroarenes HetX (X=I, Br, Cl) to [Pd0(PPh3)2] (generated from [Pd0(PPh3)4]) have been investigated in THF and DMF and the rate constants have been determined. In contrast to the generally accepted concerted mechanism, Hammett plots obtained for substituted 2-halopyridines and solvent effects reveal a reaction mechanism dependent on the halide X of HetX: an unprecedented SNAr-type mechanism for X=Br or Cl and a classical concerted mechanism for X=I. These results are supported by DFT studies.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1120-95-2

A novel series of 1,2,4-triazolyl octahydropyrrolo[2,3-b]pyrroles showing high affinity and selectivity at the DA D3 receptor is reported here. Compounds endowed with high selectivity over the hERG channel were identified and their pharmacokinetic properties thoroughly analyzed.

Purification and Some Properties of Nicotinate Phosphoribosyltransferase from Hog Liver

Purification of nicotinate phosphoribosyltransferase (NPRTase, EC 2.4.2.11) from hog liver and some of its properties were investigated.Purified enzyme was found to be homogeneous by the criterion of polyacrylamide gel disc electrophoresis and to have a molecular weight of about 120,000.The subunit molecular weight was found to be 64,000, using SDS polyacrylamide gel disc electrophoresis.The optimum pH and isoelectric point of the enzyme were 7.3-7.4 and 4.8, respectively.Mn(2+), Co(2+), and Mg(2+) were effective in meeting the NPRTase requirement for a divalent cation.ATP had a stimulative effect on the enzyme activity in the presence of Mg(2+), on the other hand, in the presence of Mn(2+), ATP had an inhibitory effect on the enzyme activity.Of the purine nucleotides examined, only ATP stimulated NPRTase activity, and GTP did not.On the contrary, all other nucleotides inhibited the activity.Nicotinate mononucleotide, which is a reaction product, inhibited NPRTase activity.Among the nicotinic acid analogues tested, only pyrazine-2-carboxylic acid inhibited the activity.Nicotinamide, quinolinic acid, adenine, and hypoxanthine were not phosphoribosylated by NPRTase.Incubation of NPRTase with SH-modifying reagents caused loss of NPRTase activity.
