New types of pinanyl-2-aminopyrimidines and pinanyl isoxazolines were synthesized from (-)-α-pinene. (-)-α-Pinene was selectively oxidized into (+)-2-hydroxy-3-pinanone, which was condensed with aromatic aldehydes to obtain 4-arylidene-2-hydroxy-3-pinanones 2a2f. Pinanyl-2-aminopyrimidines 3a3e and pinanyl isoxazolines 4a4d were prepared by cyclization of 4-arylidene-2-hydroxy-3-pinanones with guanidine hydrochloride and hydroxylamine hydrochloride under catalysis of NaOH or t-BuOK. The structures of the synthesized compounds were determined by 1H NMR, 13C NMR, FT-IR, GC-MS, and elemental analyses. Antibacterial and antifungal activities tests of the synthesized pinanyl-2-aminopyri- midines 3a3e and pinanyl isoxazolines 4a4d against C. albicans, A. niger, G. tropicalis, E. coli, S. aureus, B. subtilis, and P. fluorescens were also carried out, and it has been observed that compounds 3b and 3e had strong antibacterial effects to E. coli and B. subtilis, 3a, 3d, 4b and 4d had good activities to E. coli.

Key words: (-)-α-pinene, 4-arylidene-2-hydroxy-3-pinanones, pinanyl-2-aminopyrimidines, pinanyl isoxazolines, antibacterial activity
