Stereoselective Synthesis of α-Silylamines by the Direct Addition of Silyl Anions to Activated Imines

A highly efficient stereoselective synthesis of unusual α-silylamines via a direct silyl anion addition reaction is reported. This approach is
convergent and avoids any problematic aza-Brook shifts of the anionic intermediates. The use of enantiopure tert-butanesulfinyl imines as the
electrophiles affords exceedingly high levels of diastereocontrol for the newly formed stereogenic carbon.
