“…Recently, regioselectivity of the reaction was improved by Sharpless and Meldal by introducing Cu(I) catalyzed alkyne-azide 1,3-dipolar cycloaddition (CuAAC) to afford 1,4-disubstituted 1,2,3-triazole [19,20]. The triazole nucleus is an important pharmacophore appearing extensively in various types of pharmaceutical agents and bioactive molecules, such as anti-HIV [21], antitubercular [22], anti-inflammatory, anticancer [23], antimicrobial [24], anticonvulsant [25], V. S. Dofe et al antimalarial [26], analgesic [27], antiviral [28], antidiabetic [29], antimycobacterial [30], and anticholinesterase [31]. The biological activity of these compounds is enhanced probably due to their high aromatic stabilisation, high dipole moment, and high bonding capacity.…”
