A series of new N‐substituted benzimidazole derivatives was synthesized and their antifungal activity against Candida albicans was evaluated. The chemical step included synthesis of appropriate ketones containing benzimidazole ring, reduction of ketones to the racemic alcohols, and acetylation of alcohols to the esters. All benzimidazole derivatives were obtained with satisfactory yields and in relatively

system is amenability to single-crystal x-raystructuredetermination and this is demonstrated with an x-raystructure of a copper(II) complex. Crystal data for CuC/sub 74/H/sub 66/N/sub 12/O/sub 3/1.5 (diethyl ether) toluene are the following: monoclinic, C2/c, a = 31.240 (4) A, b = 16.769 (5) A, c = 35.199 (4) A, ..beta.. = 121.4 (1)/sup 0/; R = 0.0826, R/sub W/ = 0.0826.
