The present invention relates to monocyclic aroylpyridinones, processes for their preparation, and their use in medicaments, especially for the treatment of COPD: (formula I).
A regioselective and highly efficient synthesis of 6-amino-substituted pyridin-2(1H)-ones is presented. In situ generated propiolic acid chloride was used for the cyclization of acyclic β-keto N,S-acetals to afford the heterocyclic core. Substitution by amines led to a flexible access of the target compounds.
