Outline of Final Research Achievements

Effects of amide bases on halogen dance were investigated. Compared to the conventional lithium amides, the magnesium bisamide can control halogen dance of 2,3-dibromothiophene to provide both products that are derived from the two carbanion species. In addition, magnesium amide facilitated the formation of cycloalkanes from the enol triflates, which were prepared from the corresponding ketones in one step.

Academic Significance and Societal Importance of the Research Achievements

マグネシウムアミドを塩基として用いる2,3-ジブロモチオフェンのハロゲンダンスでは,二つの炭素アニオンを選択的に発生させることに成功した。この結果は,同一の出発物質から,異なる炭素アニオンを選択的に発生させ,多様な化合物への合成展開が可能になったことを示している。また,マグネシウムアミドを塩基として用いるシクロアルキン発生法では,これまで多段階を必要としてきたシクロアルキン前駆体の合成を大幅に短工程化できた。
