Synthesis and application in asymmetric synthesis of azacrown ethers derived from D-glucose

Abstract

New chiral monoaza-15-crown-5 derivatives and lariat ethers anellated to phenyl β-D-glucoside have been synthesized which show significant asymmetric induction as phase transfer catalysts in the Michael addition of 2-nitropropane to chalcone (84% ee) and in the Darzens condensation of phenacyl chloride with benzaldehyde (74% ee).
