  An Efficient Kinetic Resolution of Racemic Betti Base Based on an Enantioselective N,O-Deketalization

  摘要：

  [GRAPHIC]An efficient kinetic resolution of racemic Betti base with L-(+)-tartaric acid in acetone was developed based on a novel enantioselective N,O-deketalization, by which the enantiopure R- and S-enantiomers of Betti base were obtained as the corresponding NO-ketal compound and salt with L-(+)-tartaric acid, respectively, in excellent yields with a practically foolproof operation.

• Synthesis and characterization of some novel copper(II) complexes with an optically active Betti base

  日期：2012.3

  Novel Cu(II) complexes with racemic as well as optically pure 1-(alpha-amino benzyl)-2-napthol, commonly known as Betti base, and its derivative 1-(alpha-pyrrolidinyl benzyl)-2-napthol have been synthesized. The general composition of all the isolated complexes, as determined by elemental analysis, thermal analysis and FAB mass spectra, is found to be Cu(L-H)(2). The coordination of the ligand with metal has been confirmed by IR and ESR spectra of the complexes. The CD spectra of complexes with the S-form of the ligands exhibit a mirror image relationship with the CD spectra of the complexes with the corresponding R-form of the ligands. The Cu(II) complex with racemic Betti base has been characterized structurally. It crystallizes in the monoclinic space group P2(1)/c. The complexes display quasi reversible redox behavior due to the Cu(II)/Cu(I) reduction process. (C) 2012 Elsevier Ltd. All rights reserved.
