Nitromethane condensation of 2 and 5 at room temperature gave the corresponding 3-nitromethyl derivatives having D-gluco- and D-allo-configuration, respectively. The difference in the stereoselectivity was explained by the easiness of isomerization of the initial product to thermodynamically stable epimer, because the reaction temperature was essential to control the selectivity in the same reaction of 1,2 : 5,6-di-O-isopropylidene-α-D-ribo-hexofuranos-3-ulose. Reaction of 2 with hydrogen cyanide in dry pyridine followed by acetylation gave the corresponding 3,5,6-tri-O-acetyl-3-cyano derivative of D-allo-type, whereas, the reaction in water gave instantly 3-(hydroxycarbonimidoyl)-1,2-O-isopropylidene-α-D-allofuranose 3′,5-lactone, by the participation of the C5-hydroxyl group.","subitem_description_type":"Abstract"}]},"item_7_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_7_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本化学会"}]},"item_7_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1246/bcsj.50.1191","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00580132","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0009-2673","subitem_source_identifier_type":"ISSN"}]},"item_7_version_type_16":{"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":"佐藤, 憲一"}],"nameIdentifiers":[{"nameIdentifier":"5906","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Ken-ichi"}],"nameIdentifiers":[{"nameIdentifier":"5907","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉村, 寿次"}],"nameIdentifiers":[{"nameIdentifier":"5908","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshimura, Juji"}],"nameIdentifiers":[{"nameIdentifier":"5909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辛, 重基"}],"nameIdentifiers":[{"nameIdentifier":"5910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shin, Chung-gi"}],"nameIdentifiers":[{"nameIdentifier":"5911","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":"2018-11-16"}],"displaytype":"detail","filename":"佐藤・化学-006.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"佐藤・化学-006.pdf","url":"https://kanagawa-u.repo.nii.ac.jp/record/2940/files/佐藤・化学-006.pdf"},"version_id":"e1c1f29c-10f4-4a98-aa51-ac49bcc25ec6"}]},"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":"Branched-chain Sugars.
