Recent progress in the application of amidines for the synthesis of N-heterocyclic compounds
摘要
Nitrogen-containing heterocycles are an inseparable part of many biologically active compounds. Therefore, the synthesis of these structures is of great importance in the field of synthetic chemistry. Due to the presence of two nitrogen atoms in the amidine structure, this molecule can be considered as a dual nucleophile in the synthesis of various heterocycles. The current review highlights recent advances in the application of amidines, in particular, N-arylamidines, as versatile precursors in transition metal-catalyzed, and metal-free reactions for the construction of N-heterocyclic compounds.
