The synthesis of a series of (l)-tartrate-derived optically active, homochiral, dendritic fragments 1 – 5 by an iterative, convergent approach was reported. The chiroptical property of these chiral fragments was directly proportional to the number of chiral units.
据报道,通过迭代,会聚的方法合成了一系列(l)-
酒石酸衍生的旋光性,同手性,树枝状片段1-5。这些手性片段的手性与手性单元的数目成正比。
