Cinnamyl benzoate, an antimycotic compound with a sweet smell, was synthesized by the reaction between benzoyl chloride and cinnamyl alcohol in pyridine as solvent and consequently obtained as a colorless and needle-like crystal with a melting point of 37 degrees C. In comparison with benzoic acid as a food preservative, cinnamyl benzoate showed a specific antibiotic activity against dermatophytic fungi such as Trichophyton rubrum, Trichophyton violaceum and Epidermophyton floccosum over a wide pH range, but only weak activity towards other microorganisms such as Bacillus subtilis, Escherichia coli, Saccharomyces cerevisiae, Candida albicans and Aspergillus oryzae. Thus cinnamyl benzoate may have wide application as an aroma-diffusing antimycotic agent, an antimycotic shoe-deodorizer, and so on.
