以S-(-)-2,2’-联二萘酚为手性模板分子,合成出了它的两个七元环衍生物.通过对它们的旋光值、X衍射结构及构象的研究,找出了它们的螺旋结构与旋光性的关系,并对其族光大小进行了比较.此外,首次提出我们建立的螺旋片段判定规则及我们定义的ω值.
Its two seven-membered ring derivatives were synthesized with S - (-) - 2,2’-binaphthol as chiral template molecules. Their optical rotation, X-ray structure and conformation were studied. The relationship between their helical structures and their optical rotations was found out, and the family light sizes were compared.Furthermore, we first proposed the rules for determination of spiral segments and the ω values we defined.
