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", "download_preview_message": "", "file_order": 0, "filename": "SYNTHESIS_MS_Rev.pdf", "filesize": [{"value": "741.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 741500.0, "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"], "permalink_uri": "http://hdl.handle.net/2237/00028422", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2018-08-06"}, "publish_date": "2018-08-06", "publish_status": "0", "recid": "26218", "relation": {}, "relation_version_is_last": true, "title": ["Synthesis of Alkoxycarbonyldifluoromethyl-Substituted Semisquarates and Their Transformations"], "weko_shared_id": null}
