摘要

Asymmetric aldol polymerization of bis (triethylsilyl enol ether) and dialdehyde was performed in the presence of chiral N-sulfonyloxazaborolidinone as a catalyst. The polymerization occurred smoothly at low temperature (− 78° C to− 20° C) to afford optically active polymers having unique main-chain structure of β-hydroxy carbonyl repeating unit. In order to estimate the asymmetric induction during the polymerization, asymmetric aldol ...
