Reactions that were catalyzed by (S)-indline-2-carboxylic acid (30 mol%) in CHCl3/MeOH 97:3 (v/v) showed high exo-selectivities (exolendo 91:9 similar to 99:1) and enantioselectivities (75 similar to 98% ee). In contrast, reactions catalyzed by L-proline (30 mol%) under similar conditions favored the endo-cycloadduct (83:27 similar to 99:1) with modest to good enantioselectivities (31 similar to 83% ee). Based on our studies, the diastereoselective mechanism of the L-proline-catalyzed reaction was found to involve the isomerization of the exo- to the endo-cycloadduct in the presence of L-proline.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"HETEROCYCLES. 81(7):1669-1688 (2010)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Suga, Hiroyuki","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.HmShyVfp.html"},{"subitem_link_text":"Okumura, Yukihisa","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.gNDVgpAF.html"}]},"item_6_link_67":{"attribute_name":"WoS","attribute_value_mlt":[{"subitem_link_text":"Web of Science","subitem_link_url":"http://gateway.isiknowledge.com/gateway/Gateway.cgi?&GWVersion=2&SrcAuth=ShinshuUniv&SrcApp=ShinshuUniv&DestLinkType=FullRecord&DestApp=WOS&KeyUT=000281076100007"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Institute of Heterocyclic Chemistry"}]},"item_6_relation_46":{"attribute_name":"他の資源との関係：URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.heterocycles.jp/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.heterocycles.jp/","subitem_relation_type_select":"URI"}}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.3987/COM-10-11967"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3987/COM-10-11967","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright© 2010 The Japan Institute of Heterocyclic Chemistry"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-5414","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00663739","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Suga,  Hiroyuki"}],"nameIdentifiers":[{"nameIdentifier":"38108","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arikawa,  Tadashi"}],"nameIdentifiers":[{"nameIdentifier":"38109","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Itoh,  Kennosuke"}],"nameIdentifiers":[{"nameIdentifier":"38110","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okumura,  Yukihisa"}],"nameIdentifiers":[{"nameIdentifier":"38111","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakehi,  Akikazu"}],"nameIdentifiers":[{"nameIdentifier":"38112","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shiro,  Motoo"}],"nameIdentifiers":[{"nameIdentifier":"38113","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":"2015-09-28"}],"displaytype":"detail","filename":"ACR_Azomethine_Imine-6-7-10-revised.pdf","filesize":[{"value":"792.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ACR_Azomethine_Imine-6-7-10-revised.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/12488/files/ACR_Azomethine_Imine-6-7-10-revised.pdf"},"version_id":"69a6a473-d395-4bac-8c3b-eb4eba3d8c45"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ASYMMETRIC 1,3-DIPOLAR CYCLOADDITION REACTIONS OF AZOMETHINE IMINES WITH ACROLEIN CATALYZED BY L-PROLINE AND ITS DERIVATIVES","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ASYMMETRIC 1,3-DIPOLAR CYCLOADDITION REACTIONS OF AZOMETHINE IMINES WITH ACROLEIN CATALYZED BY L-PROLINE AND ITS DERIVATIVES","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1222"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-10-12"},"publish_date":"2011-10-12","publish_status":"0","recid":"12488","relation_version_is_last":true,"title":["ASYMMETRIC 1,3-DIPOLAR CYCLOADDITION REACTIONS OF AZOMETHINE IMINES WITH ACROLEIN CATALYZED BY L-PROLINE AND ITS DERIVATIVES"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:01:53.038831+00:00"}
