However, the lower reactivity of [18F]FEtBr with amine, phenol and amide functional groups than that of [11C]CH3I partly limits its wide application in the synthesis of [18F]fluoroethylated compounds. The aim of this study was to increase the reactivity of [18F]FEtBr with various nucleophilic substrates for PET tracers containing amine, phenol and amide moieties. The present strategies included (1) adding NaI into the reaction mixture of [18F]FEtBr and substrate, where [18F]FEtI is reversibly formed and becomes more reactive; 2) converting [18F]FEtBr into much more reactive [18F]FEtOTf, similar to conversion of [11C]CH3I into [11C]CH3OTf. By these efforts, the [18F]fluoroethylation efficiency of various substrates containing amine, phenol and amide groups with [18F]FEtBr/NaI and [18F]FEtOTf was significantly improved, compared with the corresponding reaction efficiency with [18F]FEtBr.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0362-4803","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Zhang, Ming-Rong"}],"nameIdentifiers":[{"nameIdentifier":"440349","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Furutsuka, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"440350","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshida, Yuichirou"}],"nameIdentifiers":[{"nameIdentifier":"440351","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Kazutoshi"}],"nameIdentifiers":[{"nameIdentifier":"440352","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 明栄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440353","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古塚 賢士","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440354","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉田 勇一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440355","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 和年","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"440356","nameIdentifierScheme":"WEKO"}]}]},"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":"How to increase the reactivity of [18F]fluoroethyl bromide: [18F]fluoroethylation of amine, phenol and amide functional groups with [18F]FEtBr, [18F]FEtBr/NaI and [18F]FEtOTf","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"How to increase the reactivity of [18F]fluoroethyl bromide: [18F]fluoroethylation of amine, phenol and amide functional groups with [18F]FEtBr, [18F]FEtBr/NaI and [18F]FEtOTf"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-06-23"},"publish_date":"2006-06-23","publish_status":"0","recid":"44330","relation_version_is_last":true,"title":["How to increase the reactivity of [18F]fluoroethyl bromide: [18F]fluoroethylation of amine, phenol and amide functional groups with [18F]FEtBr, [18F]FEtBr/NaI and [18F]FEtOTf"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:16:43.742661+00:00"}
