• has led to an ongoing search for safe and efficient chemotherapeutic agents with potent broad-spectrum antifungal activities. Some of the best known antifungal azole drugs having rational versatility in structures are miconazole (A), oxiconazole (B) and related compounds, namely aryl azoles (Figure 1

• different strategies were considered for the synthesis of the title compounds taking into account the differences in chemical behavior of purine and pyrimidine nucleobases compared to azoles. Because of their better solubility, reactivity and ease of separation of products, the reactions of the azole

• that among published methods for N-alkylation of imidazole derivatives [26][27][28][29][30][31][32][33][34], the method developed by Liu et al. [35] was the most appropriate one for N-alkylation of azoles and their derivatives, since in this method the formation of quaternary imidazolium salts is

• immunosuppressed patients, especially those suffering from AIDS or cancer, fungal infections have become a significant, often life-threatening problem [1][2]. Present treatments rely on antifungals such as polyene antibiotics (amphotericin B), nucleoside analogs (5-fluorocytosine) and azoles (fluoconazole
