The synthesis of 1-(2-alkyl-2-phenylethyl)-1H-imidazoles was accomplished starting from the corresponding phenylacetonitriles. Via alkylation, esterification, and sodium borohydride reduction-in the presence of lithium iodide-beta-phenylalconols were obtained. Mesylation of these alcohols and refluxing with imidazole in dimethylformamide furnished title compounds, which were active in vitro against dermatophytes, yeasts, other fungi, and gram-positive bacteria and in vivo as well as in vitro against Candida albicans.

interesting polycycliccompounds have been synthesized from non‐conjugated diyne systems by dualgoldcatalysis. A quaternary carbon center in the backbone and the accompanying Thorpe–Ingold effect enabled the unprecedented insertion of sp3 and sp2 CH bonds that for the first time were incorporated within the backbone of the diyne system and allowed the construction of complex polycyclic carbon scaffolds
