合成了两种带联萘酚侧基的手性聚醚,并将其应用于诱导苯乙炔对醛的不对称加成反应中.产物具有较好的对映选择性,ee值最高达95%.这种聚醚可以被简单的回收重复使用6次且催化活性基本不变.
Two chiral polyethers with side groups of binaphthol were synthesized and used to induce the asymmetric addition of phenylacetylene to aldehydes.The products had good enantioselectivities and the ee values were up to 95% The polyether can be simply recycled 6 times and the catalytic activity remains essentially unchanged.
