Sodium telluride, prepared by reducing tellurium with rongalite in dilute aqueous sodium hydroxide, readily reacts with nonactivated aryl iodides to afford symmetrical diaryl tellurides in good yields.
Eugenol (EU), inspired us to design and synthesize three different series of derivatives enhancing its parent compound’s anti-Helicobacter pylori activity. Thus, we prepared semisynthetic derivatives through (A) diazo aryl functionalization, (B) derivatization of the hydroxy group of EU, and (C) elongation of the allylradical by incorporating a chalcogen atom. The antibacterial evaluation was performed
