The synthesis of a large no. of b-substituted-1-phenethylimidazoles is described. Many appropriately N-substituted-1-(b-aminophenethyl)imidazoles and cyclic ketals derived from 2-(1-imidazolyl)acetophenones were quite active against dermatophytes. However, 1-(b-benzyloxyphenethyl)-imidazoles displayed potent, broad-spectrum activity, not only against dermatophytes but also against yeast cells (Candida albicans) and gram-pos. bacteria.
