The reaction of (1) with alcohols, as well as the base catalyzed reaction, gives alkyl hydracrylate. In the same manner, (2), after reacting with alcohols gives alkyl acetoacetate. However, (3), after reacting with alcohols, gives alkyl γ-oxybutyrate. Alkyl γ-oxybutyrate is reported to be impossible to obtained by the base catalyzed   reaction. The effects of time, temperature and diazomethane concentration on the proportions of products are demonstrated.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_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":"Matsumoto, Tadao"}],"nameIdentifiers":[{"nameIdentifier":"1533","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":"2013-02-25"}],"displaytype":"detail","filename":"nagano_nct-03-29.pdf","filesize":[{"value":"406.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nagano_nct-03-29.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/782/files/nagano_nct-03-29.pdf"},"version_id":"b88b92d9-a87a-49d6-a36a-b6dcace1e23c"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Reactions of Lactones with Alcohols in a Diazomethane-Ether Solution","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Reactions of Lactones with Alcohols in a Diazomethane-Ether Solution","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["57"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-25"},"publish_date":"2013-02-25","publish_status":"0","recid":"782","relation_version_is_last":true,"title":["Reactions of Lactones with Alcohols in a Diazomethane-Ether Solution"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T15:56:40.747175+00:00"}
