| Abstract: | Isomer of (±) polygodial was synthesized by six steps started from β cyclocitronillon, and the total yield was 19.8%. The analogue methyl amine was also synthesized. The bioassay showed that all of synthetic (±) polygodial, its methyl amine analogy, and crude extract of Polygonum hydropiper had strong antifeedant activity on aphids and the cabbage white butterfly larvae. |
