A very general reaction is presented to achieve the nucleophilic transfer of "CF3 " to chiral N-(tert-butylsulfinyl)imines in high yield and high stereoselectivity. Tetrabutylammonium difluorotriphenylsilicate (TBAT) functions as a fluoride source, and aromatic, heterocyclic, and aliphatic sulfinylimines react smoothly. The high stereoselectivity suggests that the reaction proceeds through an open
提出了非常普遍的反应,以高收率和高立体选择性实现了“ CF 3 ”向手性N-(叔丁基亚磺酰基)亚胺的亲核转移。四丁基三氟三苯基硅酸铵(TBAT)用作氟化物源,芳族,杂环和脂族亚磺酰亚胺反应平稳。高的立体选择性表明反应通过开放的过渡态进行。TMS =三甲基甲硅烷基。
