제목 | L-Proline-Catalyzed Construction of Polyfunctionalized Pyridines via Oxidative N- Annulation |
초록 | Pyridines and their derivatives are fundamental heterocyclic compounds contained in natural products and pharmaceuticals. They are also used in the synthesis of bioactive natural products and materials with photo- or electrochemical properties. Representative methods for the synthesis of pyridine derivatives mainly include condensation of 1,3-dicarbonyl compounds1 and organocatalyzed cycloaddition reactions.2 However, environmentally benign methods for the synthesis of pyridines are still highly desirable. Herein, we present L-proline catalyzed reaction for highly functionalized pyridines starting from ketones, α,β-unsaturated aldehydes, and ammonium acetate.3 This protocol proceeds via N-annulation through C-C and C-N bond formation in a single step. 1.
