摘要：
Cyclopolymerization of amino acid-derived novel dipropargyl ester and dipropargylamide was carried out using a rhodium catalyst. Polymers with cyclized structures were obtained under certain conditions. The dipropargylamide polymer exhibited a large specific rotation and an intense Cotton effect around 300 nm based on the chiral higher order structure. It adsorbed N-benzyloxycarbonyl-L-alanine more than the D-isomer, and extracted Li+, Na+, K+, and Cs+ from water phase into CH2Cl2 phase.
