Copper(ii)-catalyzed oxidative [3+2] cycloaddition reactions of secondary amines with α-diazo compounds: a facile and efficient synthesis of 1,2,3-triazoles
Copper-Catalyzed Oxalamide-Directed ortho-C–H Amination of Anilines with Alkylamines
摘要:
A copper-catalyzed oxalamide-directed ortho-C-H amination of anilines has been developed by using 1 atm of air as the sole oxidant. The protocol shows excellent functional group tolerance, and some heterocyclic amines including indole, benzothiophene, benzothiazole, quinoline, isoquinoline, and quinoxaline could be compatible in the reaction. The late-stage diversification of medicinal drugs demonstrates the synthetic utility of this protocol.
well‐developed and growing body of work in Cu catalysis, the potential of Cu to serve as a photocatalyst remains underexplored. Reported herein is the first example of visible‐light‐induced Cu‐catalyzed decarboxylative C(sp3)−H alkylation of glycine for preparing α‐alkylated unnatural α‐amino acids. It merits mentioning that the mild conditions and the good functional‐group tolerance allow the modification
