Synthesis and Herbicidal Activity of 2-(1-anilinobutylidene)-5,5-dimethyl-3-hydroxy-2-cyclohexen-1-ones

2-(1-Anilinobutylidene)-5,5-dimethyl-3-hydroxy-2-cyclohexen-1-ones의 합성과 제초활성

Fourteen 2-(1-anilinobutylidene)-5,5-dimethyl-3-hydroxy-2-cyclohexen-1-ones were prepared by condensation of 2-butanoyl-5,5-dimethyl-3-hydroxy-2-cyclohexen-1-one with various substituted anilines in good yield. These were tested for herbicidal activity against six different submerged paddy weed species. Most compounds showed significant activity against Echinochloa crus-galli and Sagittaria pygmaea with excellent tolerance to rice.

2-Butanoyl-5,5-dimethyl-3-hydroxy-2-cyclohexen-1-one과 여러 가지의 치환 아닐린의 축합반응으로 14가지의 2-(1-anilinobutylidene)-5,5-dimethyl-3-hydroxy-2-cyclohexen-1-ones들을 좋은 수율로 합성하였다. 이들 화합물들을 여섯 가지의 다른 담수조건 잡초들에 대하여 제초활성을 검색하였다. 대부분의 화합물들은 벼의 생육에 지장을 주지 않는 우수한 선택성을 가지면서 피(Echinochloa crus-galli)와 올미(Sagittaria pygmaea)에 대하여 우수한 제초활성을 보였다.
