Considering the biological and chemical relevance of guanidine containing derivatives, we have devised a novel and efficient two-step synthesis of 2-arylamino-1,4,5,6-tetrahydropyrimidines. We have found that the coupling of aryl bromides with 2-aminopyrimidine is a very effective method for the high yielding synthesis of 2-arylaminopyrimidines. Moreover, the employment of Pd-catalysed hydrogenation to selectively reduce the pyrimidine ring generates a very highyielding pathway to 2-arylamino-1,4,5,6-tetrahydropyrimidines of biological interest.

Reference of 13991-08-7. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene

In this study, six half-sandwich luminescent iridium (Ir) and ruthenium (Ru) anticancer complexes bearing P^P-chelating ligands 1,2-bis(diphenylphosphino)benzene (dppbz) and 1,8-bis(diphenylphosphino)naphthalene (dppn) were synthesized and characterized via1H-NMR spectroscopy, 31P-NMR spectroscopy, mass spectrometry, elemental analysis and X-ray crystallography. All the complexes displayed more potent anticancer activity than cisplatin towards A549 lung cancer cells and HeLa cervical cancer cells, especially the most potent iridium complex Ir3, which was 73 times more potent than cisplatin against A549 cells. Different from cisplatin, no nucleobase adducts of Ir3 were detected. With the help of the self-luminescence of complex Ir3 and confocal microscopy, it was observed that Ir3 efficiently penetrated into the A549 cells via energy-dependent active transport, and specifically accumulated in lysosomes, affected the permeabilization of the lysosomal membranes and induced caspase-dependent cell death through lysosomal damage. Both apoptosis and autophagy of the A549 cells were observed. The reactive oxygen species (ROS) elevation, reduction of the mitochondrial membrane potential and cell cycle arrest at the G0/G1 phase also contributed to the observed cytotoxicity of Ir3. We demonstrate that these half-sandwich Ir and Ru anticancer complexes have different anticancer mechanism of action from that of cisplatin, which can be developed as potential multifunctional theranostic platforms that combine bioimaging and anticancer capabilities.

Xantphos is one of the two most common ligands used in palladium catalyzed Buchwald-Hartwig amination reactions, because of its broad scope and high probability of success. It does not, however, work well with unactivated aryl chlorides. Herein NIXANTPHOS is compared to Xantphos and an array of mono- and bidentate phosphines. NIXANTPHOS outperforms Xantphos and all other bidentate ligands examined. Under the optimal reaction conditions, unactivated aryl chlorides afford the expected products in good to excellent yield with as low as 0.05 mol% (500 ppm) palladium loading.

The regioselective amination of substituted di- and trichloropyrimidines affording the 2-substituted products is reported. While aryl- and heteroarylamines require the use of a dialkylbiarylphosphine-derived palladium catalyst for high efficiency, more nucleophilic dialkylamines produce 2-aminopyrimidines under noncatalyzed SNAr conditions. The key is the use of 5-trimethylsilyl-2,4-dichloropyrimidine as a surrogate for the parent dichloropyrimidine. For more challenging cases, the 2-chloro-4-thiomethoxy analogues were prepared and exclusively afford the desired 2-aminated-4-thiomethoxypyrimidine products.
