Asymmetric allylic amination or oxidation can be achieved by reaction of an alkene with a peroxycarbamate catalysed by a chiral copper bis-oxazoline complex, and the reaction can be tuned to give either the amination or oxidation product by reagent choice.
N-(p-Toluenesulfonyl)amino group can be directly introduced at allylic or benzylic carbon by treating alkenes or alkylarenes with t-butyl N-(p-toluenesulfonyl)peroxycarbamate in the presence of Cu(II) triflate.
