A similar reaction of hydroxycyclobutenones bearing an alkenyl and alkynyl substituent did not produce any bis(butenolide)s or acetate monomers, but the 5-exo and 6-endo radical cyclization products including the unsaturated group. The oxidation of the hydroxycyclobutenones having an unsaturated substituent in the presence of alkenes afforded radical coupling products during the 5-exo radical cyclization. The reaction details, structure determination of the products, and the mechanism for the formation of the products are described.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_24_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Institute of Heterocyclic Chemistry","subitem_publisher_language":"en"}]},"item_24_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3987/COM-18-S(F)62","subitem_relation_type_select":"DOI"}}]},"item_24_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(C) 2019 The Japan Institute of Heterocyclic Chemistry","subitem_rights_language":"en"}]},"item_24_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-5414","subitem_source_identifier_type":"PISSN"}]},"item_24_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00663739","subitem_source_identifier_type":"NCID"}]},"item_24_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"438","subitem_subject_scheme":"NDC"}]},"item_24_version_type_19":{"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":"Sasaki, Jun-ichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"143656","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"143657","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ibe, Yusuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"143658","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishino, Hiroshi","creatorNameLang":"en"},{"creatorName":"西野, 宏","creatorNameLang":"ja"},{"creatorName":"ニシノ, ヒロシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"146758","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-03-03"}],"displaytype":"detail","filename":"COM-18-S(F)62.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"COM-18-S(F)62.pdf","url":"https://kumadai.repo.nii.ac.jp/record/30978/files/COM-18-S(F)62.pdf"},"version_id":"f331444d-441a-41c4-84bc-43b7a2f129e5"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-03-05"}],"filename":"Heterocycles2019,99,958–988,SI.pdf","filesize":[{"value":"6.4 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"Supporting Information","url":"https://kumadai.repo.nii.ac.jp/record/30978/files/Heterocycles2019,99,958–988,SI.pdf"},"version_id":"3264b8e5-dc8e-4bd6-b2c5-749a9716f961"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bis(butenolide)s","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Acetoxybutenolides","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Oxidative Cyclization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"5-endo cyclization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Manganese(III) acetate","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Mn(III)-BASED OXIDATIVE RADICAL RING-EXPANSION REACTION USING SQUARATE DERIVATIVES : SELECTIVE SYNTHESIS OF BIS(BUTENOLIDE)S AND THE ACETATE MONOMERS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mn(III)-BASED OXIDATIVE RADICAL RING-EXPANSION REACTION USING SQUARATE DERIVATIVES : SELECTIVE SYNTHESIS OF BIS(BUTENOLIDE)S AND THE ACETATE MONOMERS","subitem_title_language":"en"}]},"item_type_id":"24","owner":"12","path":["449"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-03-03"},"publish_date":"2020-03-03","publish_status":"0","recid":"30978","relation_version_is_last":true,"title":["Mn(III)-BASED OXIDATIVE RADICAL RING-EXPANSION REACTION USING SQUARATE DERIVATIVES : SELECTIVE SYNTHESIS OF BIS(BUTENOLIDE)S AND THE ACETATE MONOMERS"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-03-05T05:41:54.412556+00:00"}
