摘要: 环化交替的丁二烯乙醚(DVE)和马来酐(MA)共聚物是具有抗癌作用的生物活性剂,目前研究共聚物的关键是环的大小和构型问题.本文测定了共聚物的1H,13C NMR波谱,并采用2D COSY相关,J-分解等脉冲技术,结合PC-MOD分子能量和偶合常数的计算,与模型化合物相比较,从而对共振谱线进行了分析和归属.讨论了立体化学结构和能量的关系,从而证明了DVE-MA环化交替共聚物是一个包含有五环和六环结构的化合物,其含量之比为0.8:1.

Abstract: The alternating cyclocopolymer of DVE-MA possesses a wide spectrum of biological activities.including antitumor. Recent research on the structure of a variety of cyclocopolymer has raised a question about the ring structure of this cyclocopolymer. In this paper we report for the first time 2D 1H-1H COSY. 1-13 C COSY and J-resolved spectroscopy to elueidate the 400MHz NMR spectrum of eyclocopolymer of DVE-MA,combined with the PC-MOD calenlation of coupling constant and minimal energy in comparison with model compounds.We discussed the relation of stereochemistry of the copolymer to energy.

Key words: Alternating cyclopolymer of DVE-MA, PC-MOD calculation, 2D NMR
