It was accepted ligands played key role for selectivesynthesis and catalysis. A novel pyridinyltriazine skeleton ligand, the corresponding catalysts SBA-15@TZP-Ir and SBA-15@TZP-Ru were synthesized and fully characterized by modern methods. The resulting catalysts showed high catalytic activity in selectivesynthesis of useful substituted perimidines and aminopyrimidines in high yields. Additionally

The reactions of heteroaromatic aldehydes with heteroaromatic amines show significant differences depending on the heteroaromatic moieties present both in the aldehydes and in the amines, giving imines (3) or [bis-(heteroarylamino)methyl]arenes (5). The direct formation of (N-heteroaryl)heteroarylmethanamines (4) is achieved by the Leuckart-Wallach reaction. Reaction conditions for the formation of amines (4) by NaBH4 reduction of imines (3) are also reported.

The paper presents the activity trends for a novel series of phenoxyacetyl amides as human TRPM8 receptor agonists. This series encompasses in vitro activity values ranging from the micromolar to the picomolar levels. Sensory evaluation of these molecules highlights their relevance as cooling agents for oral applications. The positive outcome of the complete evaluation of N-(1H-pyrazol-3-yl)-N-(th
