Synthesis and bioactivity of salicylic acid 3-N'-benzyloxycarbonyl-β-aminobutyric ester

The plant activators such as salicylic acid and D, L-β-aminobutyric acid can induce systemic resistance acquired in the treated plants against following pathogen attack. Utilizing coordination of active moieties, the chemical activators were designed to incorporate some structural moieties from β-aminobutyric and salicylic acid ester. Nine new compounds were prepared, whose structures were confirmed by elemental analysis and 1H NMR. The bioactivity of them was tested and the results indicate that several compounds show a certain induced activity against pathogen infection.
