- Intramolecular hydrogen bonding-assisted cyclocondensation of α-diazoketones with various amines: A strategy for highly efficient Wolff 1,2,3-triazole synthesis
-
A catalytic and highly efficient Wolff's cyclocondensation of α-diazoketones with aromatic and aliphatic amines has been realized for the first time by utilizing the strategy of an intramolecular hydrogen bonding-activating carbonyl group. This approach successfully solved the challenging problem of poor condensation efficiency in Wolff 1,2,3-triazole synthesis, and constitutes a powerful method for the synthesis of highly functionalized 1,2,3-triazoles.
