- W2090187248 abstract "본 연구에서 thyme oil의 주성분인 thymol (1)과 유사한 구조를 갖는 4-isopropyl-3-methylphenol (2), 5-isopropyl-3-methylphenol (3), 4-isopropylphenol (4)과 2-isopropylphenol (5)을 출발 물질로 하여 sulfonyl ester 계열 유도체 25종을 합성하였다. IR, <TEX>$^1H$</TEX>-NMR과 GC/MS를 이용하여 이들 유도체들이 합성되었음을 확인하였다. 이들 유도체들에 대한 식물병원균의 생장 억제실험은 벼도열병균(Pyrcularia grisea), 벼잎집무늬마름병균(Rhizoctonia solani), 토마토잎마름역병균(Phytophthora infestans), 오이탄저병균(Colletotrichum orbiculare)과 오이흰가루병균(Sphaerotheca fusca)에 대하여 실시하였다. 그 결과, 2-isopropyl-5-methylphenyl o-toluenesulfonate (1a), 2-isopropylphenyl 2,4,5-trich lorobenzenesulfonate (5b)와 2-isopropylphenyl 2-methyl-5-nitrobenzenesulfonate (5e)는 각각 in vivo에서 벼도열병균(Pyrcularia grisea), 토마토잎마름역병균(Phytophthora infestans)과 오이흰가루병균(Sphaerotheca fusca)에 대하여 우수한 항균활성을 나타내었다. Twenty five compounds isopropylmethylphenyl benzenesulfonate derivatives of thymol (1), 4-isopropyl-3-methylphenol (2), 5-isopropyl-3-methylphenol (3), 4-isopropylphenol (4), and 2-isopropylphenol (5) derivatives were synthesized. These compounds were analyzed for their structural confirmation with IR, GC/MS, and <TEX>$^1H$</TEX>-NMR. Synthetic compounds were tested against phytopathogenic fungi activities such as Pyrcularia grisea, Rhizoctonia solani, Phytophthora infestans, Colletotrichum orbiculare, and Sphaerotheca fusca. 2-Isopropyl-5-methylphenyl o-toluenesulfonate (1a), 2-isopropylphenyl 2,4,5-trichloro-benzenesulfonate (5b) and 2-isopropylphenyl 2-methyl-5-nitrobenzenesulfonate (5e) showed a potent in vivo antifungal activity against Pyrcularia grisea, Phytophthora infestans and Sphaerotheca fusca." @default.
