Toward the total synthesis of 1, we have achieved the synthesis of the αβ, -unsaturated δ-lactone as a model compound bearing a bulky cyclopentanol substituent at α-position. The synthetic approach involves the following key steps: (i) Aldol coupling of cyclopentanone with α-p-methoxybenzyloxy ester, (ii) Swern oxidation of the α-hydroxy ester to afford the α-ketoester, (iii) Julia-Kocienski olefination of the α-ketoester followed by lactonization step.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10002_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "東北医科薬科大学", "subitem_publisher_language": "ja"}]}, "item_10002_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)", "subitem_rights_language": "en", "subitem_rights_resource": "https://creativecommons.org/licenses/by-nc-nd/3.0/deed.en"}]}, "item_10002_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2432-5724", "subitem_source_identifier_type": "PISSN"}]}, "item_10002_version_type_20": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "中井, 啓陽", "creatorNameLang": "ja"}, {"creatorName": "ナカイ, ケイヨウ", "creatorNameLang": "ja-Kana"}, {"creatorName": "Nakai, Keiyo", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Sayar, Noel", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "吉村, 祐一", "creatorNameLang": "ja"}, {"creatorName": "ヨシムラ, ユウイチ", "creatorNameLang": "ja-Kana"}, {"creatorName": "Yoshimura, Yuichi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "渡邉, 一弘", "creatorNameLang": "ja"}, {"creatorName": "ワタナベ, カズヒロ", "creatorNameLang": "ja-Kana"}, {"creatorName": "Watanabe, Kazuhiro", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-12-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "原著1_中井啓陽.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "海洋由来ジテルペン系天然物cristaxenicin A の合成研究:α位に高立体障害の置換基を有するδ-不飽和ラクトン化合物の合成", "objectType": "fulltext", "url": "https://tohoku-mpu.repo.nii.ac.jp/record/734/files/原著1_中井啓陽.pdf"}, "version_id": "a30a6e07-35ba-4b16-8b44-461a9067750f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "cristaxenicin A", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Julia-Kocienski olefination", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "δ-unsaturated lactone", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "海洋由来ジテルペン系天然物cristaxenicin A の合成研究:α位に高立体障害の置換基を有するδ-不飽和ラクトン化合物の合成", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "海洋由来ジテルペン系天然物cristaxenicin A の合成研究:α位に高立体障害の置換基を有するδ-不飽和ラクトン化合物の合成", "subitem_title_language": "ja"}, {"subitem_title": "Synthetic Study toward Total Synthesis of Marine Diterpenoid Cristaxenicin A: Synthesis of δ-Unsaturated Lactone Bearing α-Bulky Substituent", "subitem_title_language": "en"}]}, "item_type_id": "10002", "owner": "15", "path": ["69"], "permalink_uri": "https://tohoku-mpu.repo.nii.ac.jp/records/734", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2018-12-06"}, "publish_date": "2018-12-06", "publish_status": "0", "recid": "734", "relation": {}, "relation_version_is_last": true, "title": ["海洋由来ジテルペン系天然物cristaxenicin A の合成研究:α位に高立体障害の置換基を有するδ-不飽和ラクトン化合物の合成"], "weko_shared_id": -1}
