The main part of this work is concerned with the protection of the functional groups and the deprotection of the protecting groups using DDQ. In Chapters 2-4, three new reactions catalyzed by DDQ, i.e., tetrahydropyranylation of alcohols, deprotection of acetals and silyl ethers, were described. In Chapter 5, it was shown that the deprotection reactions were catalyzed by various π-acceptors as well as DDQ. Furthermore, a possible mechanism for the reactions was proposed. The doprotection of these protecting groups was catalyzed by acidic materials generated from the methanolysis of acceptors. In Chapter 6, the deprotection of 1,3-duthianes using 1.5 equiv. of DDQ was reported. Selective cleavage reactions of 1,3-dithiane in the presence of 1,3-dithiolane or diphenyl dithioacetal were performed. The deprotection of 1,3-dithianes was explained by the SET mechanism. In Chapter 7, the unexpected formation of benzaldehydes by the reactions of dithioacetals derived from cinnamaldehydes with DDQ was described and a possible mechanism was proposed. In Chapters 8, the author reported the reactions of DDQ with heterocyclic compounds. The reaction of DDQ with 6- methoxy-3-methylbenzofuran gave carbon-oxygen adduct. On the other hand, the reactions of DDQ with indoles gave carbon-carbon adducts. Benzofuran derivative and indoles afforded the different types of adducts. In Chapter 9, novel dibenzofuran formation from the reactions of cyclohexenyloxydibutylboranes with DDQ was described.", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "学位の種類: 博士（理学）. 報告番号: 乙第1701号. 学位記番号: 新大博（理）乙第35号. 学位授与年月日: 平成11年3月11日", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大博（理）乙第35号", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "13101B1701"}]}, "item_6_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "48470", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "種村, 潔"}]}]}, "item_6_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学"}]}, "item_6_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "ETD"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tanemura, Kiyoshi"}], "nameIdentifiers": [{"nameIdentifier": "48469", "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": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "000000342064.pdf", "filesize": [{"value": "11.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 11800000.0, "url": {"label": "本文", "url": "https://niigata-u.repo.nii.ac.jp/record/4454/files/000000342064.pdf"}, "version_id": "ab170948-5e0f-4c76-ab7a-3fc1ba0f5ac1"}]}, "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": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Studies on Useful Protection of Functional Groups and Deprotection of Protecting Groups Using 2,3-Dichloro-5,6-dicyano-p-benzoquinone(DDQ)and Related Reactions", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Studies on Useful Protection of Functional Groups and Deprotection of Protecting Groups Using 2,3-Dichloro-5,6-dicyano-p-benzoquinone(DDQ)and Related Reactions"}, {"subitem_title": "Studies on Useful Protection of Functional Groups and Deprotection of Protecting Groups Using 2,3-Dichloro-5,6-dicyano-p-benzoquinone(DDQ)and Related Reactions", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["455", "564"], "permalink_uri": "http://hdl.handle.net/10191/23704", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-10-09"}, "publish_date": "2013-10-09", "publish_status": "0", "recid": "4454", "relation": {}, "relation_version_is_last": true, "title": ["Studies on Useful Protection of Functional Groups and Deprotection of Protecting Groups Using 2,3-Dichloro-5,6-dicyano-p-benzoquinone(DDQ)and Related Reactions"], "weko_shared_id": 2}
