Synthesis and Characterization of New Functionalized 1,2, 3-Triazole-Based Acetaminophen Derivatives via Click Chemistry from Expired Commercial Acetaminophen Tablets
Abstract:We hereby describe an efficient method for the preparation of a series of new 1-substituted 1,2,3-triazole-based acetaminophen derivatives through a clean, good-yielding, simple, and expeditious procedure based on the O-propargylation reaction of the acetaminophen (APAP) obtained from expired commercial tablets and the CuBr(PPh3)3-catalyzed Huisgen reaction be-tween O-propargylated APAP and diverse organoazides prepared from commercially available anilines as available starting reagents. An interesting nitric … Show more
