Synthesis of Methyl 4,6-Di-O-ethyl-alpha-d-glucopyranoside-Based Azacrown Ethers and Their Effects in Asymmetric Reactions

Carbohydrate-based crown ethers have been reported to be able to generate asymmetric induction in certain reactions. Previously, it was proved that the monosaccharide unit, the anomeric substituent, and the sidearm could influence the catalytic activity of the monoaza-15-crown-5 macrocycles derived...
