合成了一种基于联萘酚的新型手性单体,(S)-3-(二苯羟甲基)-3'-3-乙烯基-2,2'-二羟基-1,1'-联萘(5).通过由偶氮异丁腈(AIBN)引发的自由基聚合得到聚[(S)-3-(二苯羟甲基)-3'-3-乙烯基-2,2'-二羟基-1,1'-联萘](P-5),旋光、紫外-可见光谱、圆二色谱表征结果表明P-5以单手性螺旋结构的形式存在于溶液中.考察了螺旋齐聚物P-5在催化苯甲醛与Danishefsky双烯烃的杂-Diels-Alder(HDA)反应中的不对称诱导作用,所得加和产物的ee值达71%,P-5可以被回收重复使用而保持催化活性不变.

A novel binaphthol-based monomer, 3-hydroxydiphenylmethyl-3'-vinyl-2,2'-dihydroxy-1,1'-binaphthyl was synthesized and polymerized using azodiisobutyrodinitrile (AIBN) as an initiator to afford the polymer P-5. Polarimetry, UV-Vis and circular dichroism spectroscopy characterizations indicated that the polymer existed in the form of one-handed helical structure in solution. The application of helical polymer P-5 in catalytic asymmetric hetero-Diels-Alder (HDA) reaction between benzaldehyde and Danishefsky's diene has been studied, resulting in the target product with 71% ee. P-5can be easily recovered and reused without loss of catalytic activity.
