摘　　要：以手性1,2-环己二醇为原料,选择正交保护基团和酰化试剂,通过迭代偶合法合成了聚合度从2到12的碳酸环己烯酯的离散型全同和间同寡聚物.利用核磁共振波谱和高分辨质谱精确表征了其微结构,通过比对聚碳酸环己烯酯的核磁共振碳谱中羰基碳区域各个峰的积分面积可以定量计算其立构规整度.(R,R)/(S,S)-cyclohexene-1,2-diols were used as starting materials to synthesize various isotactic and syndiotactic model compounds(oligomers with 2—12 degrees of polymerization)of poly(cyclohexene carbonate)(PCHC)through an iterative coupling method using two orthogonal protecting groups and acrylation reagents.These stereoregular oligomers were characterized by high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy.The stereoregularity of PCHC can be accurately calculated by comparing the integral area of each peak in the carbonyl carbon regions of the ^(13)C nuclear magnetic resonance spectrum.
