1-Benzhydryl -4- (5-nitro-2-furfurylideneamino) piperazine and 11 substituted analogs were prepared and examined for in vitro antimicrobial activity. The compounds were active against Bacillus cereus 7, Bacillus megaterium 122, Bacillus subtilis 104, Clostridium perfringens 13, and the tetracycline-resistant Clostridium perfringens 37.

compounds were devoid of any antimicrobial activity, but several of them inhibited T. rubrum with MIC values in the range of 0.125 to 32 µg/mL, similar or superior to those of bifonazole and clotrimazole, used as standard controls. The replacement of the imidazole ring with a triazole moiety in these compounds led to derivatives with less antifungalactivity. A preliminary SAR was undertaken on the effect

a new synthetic strategy is demonstrated, where arynes are converted into aryl anionequivalents by treatment with phosphines and a base. The addition of phosphines to arynes form the phosphonium salts, which in the presence of a carbonate base generates the aryl anionequivalent. Subsequent addition of the aryl anions with aldehydes afforded the secondary alcohols.
