Organocatalytic [3+2] 1,3-dipolar cycloaddition reactions of β-keto amides with azides catalyzed by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) have been developed. This strategy generates 1,4,5-trisubstituted 1,2,3-triazole-4-carboxamides in high yields and

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.
