Synthesis of chiral azacrown ethers derived from α-D-glucose and their catalytic properties on the asymmetric Michael addition

Three types of chiral azacrown ethers have been synthesized from (+)(4,6-O-benzylidene)-O-methyl-α-D-glucopyranoside and their catalytic properties for the asymmetric Michael addition have been investigated; enantioselectivity switching which is dependent on the azacrown ether catalysts has been achieved.
