Its chemical structure was elucidated from spectroscopic data and by synthesis. This compound caused a 35% reduction in hypocotyl length of lettuce seedling compared to the control at 25 ppm, etiolation at 100 ppm and necrosis at 200 ppm. Subsequently, we synthesized some related compounds. Among these, 4-methoxy-6-( m -chlorophenethyl)-2H-pyran-2-one was much more active, causing a 66% growth retardation at 25 ppm."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381418518506895234","@type":"Researcher","foaf:name":[{"@value":"Takashi Fujita"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418518506895235","@type":"Researcher","foaf:name":[{"@value":"Hiroyuki Nishimura"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418518506895233","@type":"Researcher","foaf:name":[{"@value":"Koichi Kaburagi"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418518506895232","@type":"Researcher","foaf:name":[{"@value":"Junya Mizutani"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00319422"}],"prism:publicationName":[{"@value":"Phytochemistry"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"1994-05","prism:volume":"36","prism:number":"1","prism:startingPage":"23","prism:endingPage":"27"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0031942200970055?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0031942200970055?httpAccept=text/plain"}],"createdAt":"2002-07-25","modifiedAt":"2019-04-19","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360848654874344576","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Synthesis of β‐Methoxyacrylate Natural Products Based on Box‐Pd<sup>II</sup>‐Catalyzed Intermolecular Methoxycarbonylation of Alkynoles"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282680188103808","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Total utilization of tropical plants Leucaena leucocephala and Alpinia zerumbet"},{"@value":"熱帯植物ギンネムおよびゲットウの総合利用(<特集>農薬活性分子の作用機構研究に関する最近の進歩)"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/s0031-9422(00)97005-5"},{"@type":"OPENAIRE","@value":"doi_dedup___::b963206af73228573d935775a8f6b5dc"},{"@type":"CROSSREF","@value":"10.1002/asia.201000292_references_DOI_8rV1DQC6sFcLjcAU8T8HOc8YJme"},{"@type":"CROSSREF","@value":"10.1584/jpestics.r07-10_references_DOI_8rV1DQC6sFcLjcAU8T8HOc8YJme"}]}
