Therefore, the cycloaddition of unprecedented CF3-substituted oxidopyridinium betaines was investigated. After the methylation of trifluoromethylated pyridin-3-ols with methyl triflate, pyridinium ions generated in-situ were treated with triethylamine in the presence of N-methylmaleimide to produce trifluoromethylated 8-azabicyclo[3.2.1]octane derivatives via (5+2) cycloaddition of the corresponding oxidopyridinium betaines. Exo/endo-selectivity varied depending on the positions of the CF3 substituents; endo-products were preferred in the reactions of oxidopyridinium betaines with the CF3 group at the 2- or 6-positions, whereas the 5-CF3-substituted betaine exclusively produced an exo-product. Moreover, unique regio- and stereoselectivities have been observed in the reactions of 2- or 6-CF3-substituted oxidopyridinium betaines with vinyl sulfones and trans-1,2-disubstituted alkenes. To gain insight into the reactivity of trifluoromethylated oxidopyridinium betaines, computational investigations were also conducted.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Wiley", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1002/asia.202300211", "subitem_relation_type_select": "DOI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "\"This is the peer reviewed version of the following article: [Yamamoto, Y., Tazawa, S., Tadano, R., Yasui, T., Chem.
