In order to improve the synthetic utility of this reaction, it is necessary to control the regioselectivity of these ring transformations. In the present work, we performed DFT calculation to realize the selectivity of two ring transformation products. In cases of adduct intermediates derived from cyclohexanone and cyclooctanone, the 2-attack proceeds preferably to give condensed pyrimidines. On the other hand, the adduct intermediate derived from cycloheptanone undergoes the 4-attack predominantly to afford condensed nitropyridone.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_35": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier Ltd."}]}, "item_2_relation_13": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1016/j.tetlet.2012.12.020", "subitem_relation_type_select": "DOI"}}]}, "item_2_version_type_18": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_ab4af688f83e57aa", "subitem_version_type": "AM"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Nishiwaki, Nagatoshi"}], "nameIdentifiers": [{"nameIdentifier": "903", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sugimoto, Ryuichi"}], "nameIdentifiers": [{"nameIdentifier": "904", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Saigo, Kazuhiko"}], "nameIdentifiers": [{"nameIdentifier": "905", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kobiro, Kazuya"}], "nameIdentifiers": [{"nameIdentifier": "906", "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": "2019-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "27-23.pdf", "filesize": [{"value": "135.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 135800.0, "url": {"label": "27-23.pdf", "url": "https://kutarr.kochi-tech.ac.jp/record/227/files/27-23.pdf"}, "version_id": "221ab9bc-5d95-432f-bd51-6826ba6ab8e3"}]}, "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": "Mechanistic aspect of ring transformations in the reaction of 5-nitro-4-pyrimidinone with acetophenone derivatives and cycloalkanones depending on the electron density/ring size of the ketone", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Mechanistic aspect of ring transformations in the reaction of 5-nitro-4-pyrimidinone with acetophenone derivatives and cycloalkanones depending on the electron density/ring size of the ketone"}]}, "item_type_id": "2", "owner": "2", "path": ["5"], "permalink_uri": "http://hdl.handle.net/10173/1349", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-25"}, "publish_date": "2016-03-25", "publish_status": "0", "recid": "227", "relation": {}, "relation_version_is_last": true, "title": ["Mechanistic aspect of ring transformations in the reaction of 5-nitro-4-pyrimidinone with acetophenone derivatives and cycloalkanones depending on the electron density/ring size of the ketone"], "weko_shared_id": -1}
