text: The White catalyst can effect both branched and linear regioselective allylic C-H aminations.  In order to promote nucleophilic attack at the internal terminus of the π-allyl to generate branched product, a tethered N-sulfonyl carbamate nucleophile is used.  This strategy has been applied to the synthesis of 1,2 and 1,3-amino alcohols.  The amination proceeds with high yields and good diastereoselectivity, and the products may be readily elaborated to amino acids and other synthetic intermediates and natural products.  Key to the development of the reaction was identification of a very acidic nitrogen nucleophile with a pKa close to acetic acid, as more basic nucleophiles divert reactivity to aminopalladation.  The intermolecular version of the allylic C-H amination is also known.  Using methyl N-tosyl carbamate nucleophile, the linear E-allylic amine products are obtained from α-olefin substrates.  It has been shown that functionalization of the π-allyl intermediate may be promoted by chromium(III) salen chloride activation of the electrophile, or Hunig's base activation of the nucleophile.
