Synthesis of Methylated β-Cyclodextrins Derived Optically Active Poly(N-diphenylmethyl maleimide)

Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080

Received Date: 26 September 1996

The methylated β-cyclodextrins derived optically active polymers are first synthesized through asymmetric polymerization of N-diphenylmethyl maleimide with lithium salt of heptakis (2,6-O-dimethyl) β-cyclodextrin (DM-β-CD) as an initiator.The resulting polymers show negative specific rotation which is opposite in sign to that of DM-β-CD.The asymmetric induction is further confirmed by circular dichroism.The structure is characterized by IR and NMR spectroscopies.
