AbstractUnder microwave irradiation, a series of novel aryl esters of N-Cbz-amino acids were synthesized in moderate yields by condensation reactions of N-Cbz-amino acids with substituted phenols in the presence of DCC and pyridine, but the reaction time was greatly shortened. The target products were characterized by 1H NMR, 13C NMR, IR and MS. A preliminary bioactivity study of the target products against organisms was investigated. The results showed they exhibited some fungicidal and insecticidal activities, and the activity against the phytopathogens was higher than against pest insects.
