  • 우렁쉥이 껍질로부터 추출한 카로테노이드 색소의 식품첨가물로서의 이용 가능성을 알아보기 위하여 SDE(simultaneous distillation and extraction/concentration) 장치를 이용하여 휘발성 화합물을 추출하였다. 이를 GC 및 GC-MS로 분석하여 총 63성분의 휘발성 화합물을 동정하였고, 대부분의 화합물이 카로테노이드의 가열분해로 생성되어지는 것으로 나타났다. 동정된 화합물중 대표적인 화합물은 1,3,5-trimethylbenzene, 3,5,5-trimethyl-3-cyclohexen-1-ol, 3,5,5-trimethyl-3-cyclohexen-1-one, 1,1,2,3-tetramethyl-2-cyclohexen-5-ol, 1,1,2,3-tetramethyl-2-cyclohexen-5-one, 2,3,4,4-tetramethyl-6-hydroxy-2-cyclohexene-1-one, 1,2,3,8-tetrahydro-3,3,6-trimethyl-1-naphtol, dihydroacetinidolide, ${\beta}-ionone$, 2-(1,1,5-trimethyl-3-hydroxy-5-cyclohexen-6-yl)-1-to-lylethene, 2,6-dimethyl-8-(1,1,5-trimethyl-3-hydroxy-5-cyclohexen-6-yl)-1,3,5-octatriene-7-yne 등 이었다. 이중 몇가지 화합물의 생성기작도 추정해 보았다.

  • 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.

  • Oxidation of isophorone by various fungi was examined. Aspergillus niger oxidized isophorone to 4-hydroxyisophorone, 3-hydroxymethyl-5,5-dimethyl-2-cyclohexen-1-one and 5-hydroxymethyl-3,5-dimethyl-2-cyclohexen-1-one. 4-Oxoisophorone obtained by chromic acid oxidation of 4-hydroxyisophorone was transformed to 2,3,5-trimethyl-p-benzoquinone by acid treatment.

  • 3-Aryltetrahydro-1,2-benzisoxazolin-4-one derivatives were prepared by regioselective 1,3-dipolar cycloaddition reactions of various aryl nitrile oxides with 2-cyclohexen-1-one. The structures of these compounds were designed as a modifications of triketone herbicides and showed good herbicidal activity.
