Some peculiar features of two most commonly used catalytic systems (Cul and CuSOVsodium ascorbate) controlling the regioselectivity of 1,3-dipolar cycloaddition of azides to terminal alkynes have been studied. Their potentialities, main disadvantages, and limitations have been demonstrated by a number of examples, including reactions of low-molecular-weight azides and alkynes containing heterocyclic
Metal‐free triazole turns: 1,5‐Disubstituted peptidyl triazoles are obtained regioselectively from the 1,3‐dipolar cycloaddition of peptidyl phosphoranes and azides. Peptide turns are thus formed that contain a conformationally locked cis peptide bond. Being regioselective and free of heavy metals, this reaction may find broad application in chemical biology and medicinal chemistry.

on the modifications of diarylpyrimidines as HIV-1non-nucleosidereversetranscriptaseinhibitors (NNRTI) and reported crystallography study, novel diarylnicotinamide derivatives were designed with a “triazole tail” occupying the entrance channel in the NNRTI binding pocket of the reversetranscriptase to afford additional interactions. The newly designed compounds were then synthesized and evaluated
Design and synthesis of 4-anilinoquinazolines as Raf kinase inhibitors. Part 1. Selective B-Raf/B-RafV600E and potent EGFR/VEGFR2 inhibitory 4-(3-hydroxyanilino)-6-(1H-1,2,3-triazol-4-yl)quinazolines
This paper presents the design and synthesis of 4-(3-hydroxyanilino)-6-(1H-1,2,3-triazol-4-yl)quinazolines of scaffold 9 as selective B-Raf/B-RafV600E and potent EGFR/VEGFR2 kinase inhibitors. Total 14 compounds of scaffold 9 having different side chains at the triazolyl group with/without fluoro substituents at the anilino group were synthesized and investigated. Among them, 9m with a 2-carbamoylethyl
