  A simple strategy for the synthesis of highly symmetric macrocycles incorporating carbohydrates is presented. The application of this strategy to the synthesis of optically active tetra-gluco-24-crown-8 (1), bis-gluco-15-crown-5 (3), and bis-gluco-21-crown-8 (5) is described. Preliminary studies showed that macrocycles 1, 3 and 5 complex ammonium salts. These macrocyclic compounds have been used as

• Simple chiral crown ethers complexed with potassium tert-butoxide as efficient catalysts for asymmetric Michael additions

  日期：1989.1

  Simple C2-symmetric chiral crown ether 1 complexed with KOtBu was found to work as an efficient chiral catalyst in Michael additions to cause high asymmetric induction. The results with various chiral crown ethers as catalysts suggest that diaxial-like conformation of the vicinal methyl groups of 1·potassium enolate complex is responsible for the chiral induction.

  Crown ethers anellated to glucose units have been used to catalyse the enantioselective Michael addition of methyl phenylacetate to methyl acrylate in high chemical yields in up to 84% enantiomeric excess. A novel CH-acid deracemization has also been discovered and the mechanistic rationale of the asymmetric induction is discussed. The proposed mechanism of the addition was also substantiated by molecular
