The compatibility of the highly reactive EtO2CCF2 group in ring transformations of the obtained semisquarate is investigated. Various EtO2CCF2-substituted, highly functionalized compounds, such as quinones, tetronates, cyclopentenones and a bicyclo-[3.2.0]heptenone, are successfully synthesized by ring transformations of the EtO2CCF2-substituted semisquarate. Also, an allylO2CCF2-substituted semisquarate is prepared and converted into the corresponding tetronate. Subsequent palladium-catalyzed deallylation followed by condensation of the resulting carboxylic acid with several amines under mild conditions affords the corresponding \u03b1,\u03b1-difluoroamides in good yields.","subitem_description_type":"Abstract"}]},"item_10_description_5":{"attribute_name":"\u5185\u5bb9\u8a18\u8ff0","attribute_value_mlt":[{"subitem_description":"\u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2019-04-01","subitem_description_type":"Other"}]},"item_10_publisher_32":{"attribute_name":"\u51fa\u7248\u8005","attribute_value_mlt":[{"subitem_publisher":"Georg Thieme Verlag"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1055/s-0036-1591887","subitem_relation_type_select":"DOI"}}]},"item_10_select_15":{"attribute_name":"\u8457\u8005\u7248\u30d5\u30e9\u30b0","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0039-7881","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"\u8457\u8005","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kurohara, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"78622","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Jiyue, Jiang"}],"nameIdentifiers":[{"nameIdentifier":"78623","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibuya, Masatoshi"}],"nameIdentifiers":[{"nameIdentifier":"78624","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamamoto, Yoshihiko"}],"nameIdentifiers":[{"nameIdentifier":"78625","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"\u30d5\u30a1\u30a4\u30eb\u60c5\u5831","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-04-01"}],"displaytype":"detail","filename":"SYNTHESIS_MS_Rev.pdf","filesize":[{"value":"741.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SYNTHESIS_MS_Rev","url":"https://nagoya.repo.nii.ac.jp/record/26218/files/SYNTHESIS_MS_Rev.pdf"},"version_id":"1c20370c-2dbe-43b1-ac7d-3a944c4a6718"}]},"item_keyword":{"attribute_name":"\u30ad\u30fc\u30ef\u30fc\u30c9","attribute_value_mlt":[{"subitem_subject":"squarate","subitem_subject_scheme":"Other"},{"subitem_subject":"ring expansion","subitem_subject_scheme":"Other"},{"subitem_subject":"fluorine","subitem_subject_scheme":"Other"},{"subitem_subject":"quinones","subitem_subject_scheme":"Other"},{"subitem_subject":"tetronates","subitem_subject_scheme":"Other"},{"subitem_subject":"cyclopentenones","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"\u8a00\u8a9e","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"\u8cc7\u6e90\u30bf\u30a4\u30d7","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Synthesis of Alkoxycarbonyldifluoromethyl-Substituted Semisquarates and Their Transformations","item_titles":{"attribute_name":"\u30bf\u30a4\u30c8\u30eb","attribute_value_mlt":[{"subitem_title":"Synthesis of Alkoxycarbonyldifluoromethyl-Substituted Semisquarates and Their Transformations"}]},"item_type_id":"10","owner":"1","path":["1903/1904/1905"],"pubdate":{"attribute_name":"\u516c\u958b\u65e5","attribute_value":"2018-08-06"},"publish_date":"2018-08-06","publish_status":"0","recid":"26218","relation_version_is_last":true,"title":["Synthesis of Alkoxycarbonyldifluoromethyl-Substituted Semisquarates and Their Transformations"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2021-03-01T11:49:59.120759+00:00"}
