摘要：

Five chiral alpha-D-glucose-based monoaza-15-crown-5 ethers with a phosphonoalkyl side chain 5a-e have been synthesized. The substituent at the nitrogen atom has a major influence on the cation extraction ability of the azacrown. The new lariat ethers 5a-e show significant asymmetric induction as phase transfer catalysts in the Michael addition of 2-nitropropane to chalcone. (C) 1999 Elsevier Science Ltd.
