Examination was made of acylation reactions of (+) -2-pinene (1), (-) -2 (10) -pinene (2) and (+) -1-p-menthene (3) with acid anhydrides (acetic anhydride and propionic anhydride) in the presence of synthetic zeolites and the following results were obtained. With US-Y type zeolites, (4) (13) were obtained from (1) (3) as the main products, respectively and evaluated on the basis of odor ; (9) emitted odors that would qualify them as flavor agents. The antimicrobial activity of acylated compounds (4) (13) toward Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Aspergillus niger and Penicillium citrinum was also examined and it was found that compound (7) (at 100 μg/mL) derived from (1) and (2), completely inhibited the growth of B. subtilis.
