to obtain the chiral polyesters. These cinchona-based chiral polyesters were successfully applied as polymericorganocatalysts in the asymmetricMichaeladditionreaction. The chiral polyesters bearing free OH groups at the C6′ position of the quinoline rings showed high catalytic activities (up to 97% isolated yield) and good enantioselectivities (up to 92% ee) in the Michaeladdition of anthrone to
