  • Title: Cu(II)-catalyzed intermolecular amidation of C-acylimine: a convenient access to gem-diamino acid derivatives.
    Author: Zhu S, Dong J, Fu S, Jiang H, Zeng W.
    Journal: Org Lett; 2011 Sep 16; 13(18):4914-7. PubMed ID: 21861453.
    Abstract:
    C-Acylimines 1 undergo intermolecular amidation with amides 2 to produce monoacyl gem-diamino acid derivatives 3 upon treatment with Cu(OTf)(2) (20 mol%)/ PPh(3) (20 mol%) under mild conditions. This method provides an efficient access to gem-diamino acid equivalents with good to excellent yields.
