Development of Cleavage Reactions of C-O and N-S Bonds Promoted by Novel Low-Valent Titanium Reagents and Their Synthetic Applications

在低价钛促进的C-O键和N-S键断裂反应中，开展了环氧化合物的自由基还原开环反应，包括立体选择性反应和磺酰胺、磺酰酯的S-N键断裂反应。此外，还发现了低价钛的选择性生成、氧杂环丁烷的自由基开环和还原McMurry型偶联反应等新的反应。

In this research on low-valent titanium-promoted C-O and N-S bondcleavage reactions, radical reductive ring-opening reaction of epoxides includingstereoselective reactions and S-N bond cleavage of sulfonamides and sulfonylesters havebeen developed. In addition, novel valence-selective generation of low-valent titanium,radical ring-opening of oxetanes and reductive McMurry-type coupling reaction have beendiscovered.
