Amide Synthesis by Nucleophilic Attack of Vinyl Azides

open access: yesAngewandte Chemie, 2014
AbstractA method for the synthesis of amide‐containing molecules was developed using vinyl azides as an enamine‐type nucleophile towards carbon electrophiles, such as imines, aldehydes, and carbocations that were generated from alcohols in the presence of BF3⋅OEt2.

Ruthenium-catalyzed azide alkyne cycloaddition reaction: scope, mechanism and applications [PDF]

open access: yes, 2016
The ruthenium-catalyzed azide alkyne cycloaddition (RuAAC) affords 1,5-disubstituted 1,2,3-triazoles in one step and complements the more established copper-catalyzed reaction providing the 1,4-isomer.

Copper-Catalyzed Amination of Vinyl Azides to α-Ketoamides

open access: yesSynOpen, 2019
An efficient approach for the amination of vinyl azides with N,N-dialkylacylamides has been developed. By using this protocol, structurally important α-ketoamides can be easily synthesized.
