Metal-free catalyst for the chemoselective methylation of amines using carbon dioxide as a carbon source

N-methylation of amines is an important step in the synthesis of many pharmaceuticals and has been widely applied in the preparation of other key intermediates and chemicals. Therefore, the development of efficient methylation methods has attracted considerable attention. In this respect, carbon dioxide is an attractive C1 building block because it is an abundant, renewable, and nontoxic carbon source. Consequently, we developed a highly chemoselective, metal-free catalytic system that operates under ambient conditions for the N-methylation of amines. The methylation of amines with CO2 as C1 source and Ph2SiH2 as reducing agent was achieved with an N-heterocyclic carbene (NHC) as the catalyst. The catalyst is tolerant toward a variety of functional groups (including esters and ethers, nitro, nitrile, and carbonyl groups, and unsaturated C-C bonds); the reaction uses commercially available reagents and can be performed on a gram scale.

Magnetic properties of dinuclear copper(II) complexes with a N6 pyridazine-derived ligand

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.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Design, synthesis and evaluation of MCH receptor 1 antagonists – Part II: Optimization of pyridazines toward reduced phospholipidosis and hERG inhibition

Abstract Despite recent success there remains a high therapeutic need for the development of drugs targeting diseases associated with the metabolic syndrome. As part of our search for safe and effective MCH-R1 antagonists for the treatment of obesity, a series of 3,6-disubstituted pyridazines was evaluated. During optimization several issues of the initial lead structures had to be resolved, such as selectivity over related GPCRs, inhibition of the hERG channel as well as the potential to induce phospholipidosis. Utilizing property-based design, we could demonstrate that all parameters can significantly be improved by consequently increasing the polarity of the compounds. By this strategy, we succeeded in identifying potent and orally available MCH-R1 antagonists with good selectivity over M1 and 5-HT2A and an improved safety profile with respect to hERG inhibition and phospholipidosis.
