Lithium salt is generally formed by a mixture of optically active alcohol and n-butyllithium as a metal source, which is too sensitive to moisture to handle in air. However, if n-butyllithium is replaced by another lithium source which is stable in air, a more convenient reaction system results. In this study, we examined the enantioselective reduction of acetophenone using lithium hydroxide instead of n-butyllithium as the metal source. Similar reactivity of the reduction was obtained when tetrahydrofuran was the solvent. In contrast, enantioselectivites were lower than when n-butyllithium was used. These results indicate that the geometry of extracoordinated silicate as an active species is affected by the coordination of water molecules.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03896692","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00408518","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"430","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nishikori, Hisashi","creatorNameLang":"en"},{"creatorName":"錦織, 寿","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"68770","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, Tomofumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"68771","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":"2016-10-27"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2010-03-16"}],"filename":"S04Hisashi Nishikori.pdf","filesize":[{"value":"259.4 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"S04Hisashi Nishikori.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/4346/files/S04Hisashi Nishikori.pdf"},"version_id":"59c3cd00-f205-4f63-b6fc-8c8d57669255"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"asymmetric reduction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lithium-alkoxide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lithium hydroxide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"and solvent effect","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A Convenient Method for Asymmetric Reduction of Acetophenone using Lithium Hydroxide","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Convenient Method for Asymmetric Reduction of Acetophenone using Lithium Hydroxide","subitem_title_language":"en"}]},"item_type_id":"7","owner":"29","path":["42","5041"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-06-16"},"publish_date":"2010-06-16","publish_status":"0","recid":"4346","relation_version_is_last":true,"title":["A Convenient Method for Asymmetric Reduction of Acetophenone using Lithium Hydroxide"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2024-12-16T07:07:04.953454+00:00"}
