摘要:
                                The sequential Sonogashira coupling/intramolecular azide cycloaddition (Huisgen cycloaddition) protocol was performed onto N-(2-iodophenyl)-2-azidoacetamide as the acyclic precursor giving tricyclic 1,2,3-triazolo-[5,1-d][1,4]benzodiazepin-2-ones. These target products were thus obtained through a three-step synthesis in variable yields depending upon the substituent placed onto the acetylenic counterpart. The influence of catalyst concentration, reaction temperature and reaction medium upon cycloadduct yields were also studied.
