摘要：

[GRAPHICS] [Cu(S,S)-t-Bu-box](OTf)(2) (1) catalyzes the enantioselective amination of enolsilanes with azodicarboxylate derivatives. Isomerically pure enolsilanes of aryl ketones, acylpyrroles, and thioesters added to the azo imide in greater than 95% ee. The use of an alcohol additive was critical to achieving catalyst turnover.
