Iron-Catalyzed C−O Bond Activation for the Synthesis of Propargyl-1,2,3-triazoles and 1,1-Bis-triazoles
摘要:
The FeCl(3)-catalyzed triazole propargylation was developed. This transformation was suitable for a large scope of substituted propargyl alcohols, giving the corresponding propargyl triazoles In excellent yields (up to 96%). Further derivatization produced the 1,1-bis-triazoles in excellent yields and regioselectivity, which could be applied as potential transition metal ligands or new reagents.
The three-component reaction of benzotriazoles, aldehydes, and alkynes has been carried out for the first time using zinc bromide as a catalyst. The corresponding propargylbenzotriazoles are formed in high yields (79-97%) within 6-10 hours.
