The present application relates to novel substituted annellated pyrimidines, methods for production thereof, use thereof alone or in combinations for treating and/or preventing diseases and use thereof for the production of medicinal products for treating and/or preventing diseases, in particular for treating and/or preventing cardiovascular diseases.
catalyst for direct synthesis of cyclicureas from CO2 and diamines even at a low CO2 pressure of 0.3 MPa. 2-Propanol is the most preferable solvent to provide good selectivity. The system composed of a CeO2 catalyst and a 2-propanol solvent is applied to various diamines to provide the corresponding cyclicureas in high yields (78–98%), including six-membered-ring ureas that are difficult to be synthesized

gold(I)–ethylene π-complexes containing a family of bulkyphosphine ligands has been prepared. The use of these sterically congested ligands is crucial to stabilize the gold(I)–ethylene bond and prevent decomposition, boosting up their catalytic performance in the highly underexplored hydroamination of ethylene. The precatalysts bearing the most sterically demanding phosphines showed the best results reaching full
