On the basis of such an association shift as well as the results obtained from solvent shift experiments with the lactams 5,6,15,and 17-19,the lactam CO and the conjugated C=C absorptions observed for each of the α, β-unsaturated lactams 14-19 in the 1590-1670 cm^<-1> region were differentiated from each other. As a result, it has now become clear that in six-membered lactams the carbonyl frequency is slightly (10-20 cm^<-1>) lowered by conjugation with a double bond, in line with the usual lowering. This is the opposite of what has been proposed in the literature. In addition, the deuterated α, β-unsaturated lactam 24 was prepared from the exocyclic methylene lactam 23 by treatment with NaOD in a mixture of D_2O and EtOD. This deuterium labeling was found to decrease the frequency of the 1666 cm^<-1> absorption, assigned to the C=C stretching vibration, by 17 cm^<-1>, supporting the correctness of the above differentiation.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本薬学会"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1248/cpb.33.2697","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00602100","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0009-2363","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"Fujii, Tozo"}],"nameIdentifiers":[{"nameIdentifier":"26757","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takai, Yukimi"}],"nameIdentifiers":[{"nameIdentifier":"26758","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohba, Masashi"}],"nameIdentifiers":[{"nameIdentifier":"26369","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60115219","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=60115219"},{"nameIdentifier":"60115219","nameIdentifierScheme":"研究者番号","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000060115219"}]},{"creatorNames":[{"creatorName":"Kogen, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"26759","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oki, Michinori"}],"nameIdentifiers":[{"nameIdentifier":"26760","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":"2017-10-03"}],"displaytype":"detail","filename":"PH-PR-OHBA-M-2697.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PH-PR-OHBA-M-2697.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/14905/files/PH-PR-OHBA-M-2697.pdf"},"version_id":"c2e99d75-67bf-416d-ac4f-35ee1704b11a"}]},"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":"Lactams.
