    enantioselective conjugate addition of cyanide to α,β-unsaturated N-acylpyrroles was developed using the chiral gadolinium catalyst generated from Gd(OiPr)3 and d-glucose-derived ligand 2. Generally high enantioselectivity was obtained from a wide range of substrates; substrates with β-aryl and β-vinyl substituents and α,β-disubstituted substrates can now be used.

  • Toward a rational design of the assembly structure of polymetallic asymmetric catalysts: design, synthesis, and evaluation of new chiral ligands for catalytic asymmetric cyanation reactions
    作者:Ikuo Fujimori、Tsuyoshi Mita、Keisuke Maki、Motoo Shiro、Akihiro Sato、Sanae Furusho、Motomu Kanai、Masakatsu Shibasaki
    DOI:10.1016/j.tet.2007.02.081
    日期:2007.6
    New chiral ligands (4 and 5) for polymetallic asymmetric catalysts were designed based on the hypothesis that the assembled structure should be stable when made from a stable module 8. A metal-ligand 5:6+mu-oxo+OH complex was generated from Gd((OPr)-Pr-i)(3) and 4 or 5, and this complex was an improved asymmetric catalyst for the desymmetrization of meso-aziridines with TMSCN and conjugate addition of TMSCN to alpha,beta-unsaturated N-acylpyrroles, compared to the previously reported catalysts derived from 1-3. These two groups of catalysts produced opposing enantioselectivity even though the ligands had the same chirality. The functional difference in the asymmetric catalysts is derived from differences in the higher-order structure of the polymetallic catalysts. (C) 2007 Elsevier Ltd. All rights reserved.

    Disclosed is a novel asymmetric ligand which can be synthesized by a short process at low cost and is capable of exhibiting higher catalytic activity and enantioselectivity than the conventional ligands derived from sugars. Also disclosed are a method for producing such an asymmetric ligand, and a catalyst using such an asymmetric ligand. Specifically disclosed is a ligand represented by the general formula I below or the like. (In the formula, R 1 and R 2 independently represent 0-5 substituents; X represents P, As or N; m represents an integer of 0-7; n represents an integer of 0-3; A 1 -A 4 independently represent hydrogen, fluorine, chlorine, bromine, benzoyl or acetyl, or alternatively A 2 and A 3 combine together to form a ring.)
