  • Title: Enantioselective direct aminalization with primary carboxamides catalyzed by chiral ammonium 1,1'-binaphthyl-2,2'-disulfonates.
    Author: Hatano M, Ozaki T, Sugiura Y, Ishihara K.
    Journal: Chem Commun (Camb); 2012 May 21; 48(41):4986-8. PubMed ID: 22506271.
    Abstract:
    A highly effective catalytic enantioselective direct aminal synthesis was developed. Chiral ammonium 1,1'-binaphthyl-2,2'-disulfonates, which were prepared in situ from (R)-BINSA and achiral amines, promoted the enantioselective addition of primary amides to aromatic aldimines.
