What is Highly stereoselective synthesis of chiral aldol polymers using repeated asymmetric Mukaiyama aldol reaction about?
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 (2788C to 2208C) to afford optically active polymers having unique main-chain structure of b-hydroxy carbonyl repeating unit. In order to estimate the asymmetric induction during the polymerization, asymmetric aldol reaction of triethylsilyl enol ether and benzaldehyde was studied as a model reaction. Optical purity of the chiral polymers obtained from the asymmetric polymerization was determined by using 1 H NMR analysis after their chiral derivatization with (R)-O-acetylmandelic acid.
