The present invention refers to the field of chemical compounds bearing a 1,2,3-triazole ring of formula (I) and possessing guanidino and carboxylic groups or their isosteres, their preparation by Cu-catalyzed "click-chemistry", and medical - diagnostic use in pathologies where angiogenesis is altered, for example pathologic conditions of tumor origin, tumor metastasis, osteoporosis, and rheumatoid arthritis.
Here, we report the novel synthesis of N-(acyloxy)phthalimides and their analogues as redox-active esters in the presence of propylphosphonic anhydride (T3P®) reagent using 2-methyltetrahydrofuran as a green solvent under mild reaction conditions. Our convenient technique provides a chromatography-free access to these remarkable synthetic intermediates with a wide substrate scope. By using our synthetic
