The very efficient addition of α,α‐difluoro‐α‐(trimethylsilyl)acetamides to aldehydes, ketones and N‐(tert‐butanesulfinyl)imines is described. The reaction is promoted by a catalytic amount of tetra‐n‐butylammonium diphenyltrifluorosilicate (TBAT) and high yields, as well as very high stereoselectivities in the case of N‐(tert‐butanesulfinyl)imines, are achieved. The synthetic potential of this method
A copper‐catalyzed oxidative amination of unactivated internal alkenes has been developed. The Wacker‐type oxidative alkene amination reaction is traditionally catalyzed by a palladiumthrough a mechanism involving aminopalladation and β‐hydride elimination. Replacing the precious and scarce palladium with a cheap and abundant copper for this transformation has been challenging because of the difficulty
the highly diastereoselective synthesis of chiral homoallylic amines by Zn-mediated allylation of chiral N-tert-butanesulfinyl imines at room temperature was developed. By simply tuning the reaction conditions, the method allows the achievement of a highly remarkable opposite stereocontrol, affording the desired stereochemical outcome in good yield and with excellent diastereoselectivity (up to 98%

[reaction: see text] Optically active cis-2-substituted vinylaziridines are synthesized by the reaction of N-tert-butylsulfinylimines with telluroniumylides with excellent diastereoselectivity in good to excellent yields.
