摘要： 在晶(固)态下,化合物邻苯二甲酸L-(+)-2,3-O-亚异丙基苏力糖酯存在两种不同的构象形式,利用螺旋片段判定规则及ω值,结合X射线衍射数据及扭转角数据,对这两种构象形式的所有螺旋片段进行了分析,尽管两种构象形式的净值螺旋性相反,但仍然得出总净值螺旋性与旋光方向一致的结论.

Abstract: In the state of crystal L (+)-2,3-Oisopropylidene threitol phathalate 1 exists in the form of two conformational isomer. Dealing with its structure and torsion angles we found and analyzed all of helical segments in the two conformational isomer with “the Judging Rule of Determining Rule of Identifying Rule of Helical Segments” and ω values. Although the two conformational isomers have opposite net helicities, we still come to the conclusion that the total net helicity of compound 1 was consistent with its direction of optical rotation.

Key words: Helical structure, Optical rotation, Conformation, L-(+)-2,3-O-Isopropylidene threitol phathalate
