  • Title: N,N'-dioxide-Cu(OTf)(2) complex catalyzed highly enantioselective amination reaction of N-acetyl enamide.
    Author: Chang L, Kuang Y, Qin B, Zhou X, Liu X, Lin L, Feng X.
    Journal: Org Lett; 2010 May 21; 12(10):2214-7. PubMed ID: 20402479.
    Abstract:
    The N,N'-dioxide-Cu(OTf)(2) complexes were applied in the asymmetric amination reaction of N-acetyl enamides with dialkyl azodicarboxylate, giving the corresponding products in good yields with high enantioselectivities (up to 91% ee). Precursors of vicinal diamine were readily obtained with excellent diastereoselectivities (>95:5) by NaBH(4) reduction.
