A series of chiral C 2-symmetrical macrocycles containing two α-amino acids and two biaryl subunits have been designed and synthesized in moderate yields (36-53%). The absolute configurations of biaryl motifs in these chiral macrocycles were established by X-ray crystal structure analysis and CD measurements.
我们设计并合成了一系列含有两个δ-
氨基酸和两个双芳基亚基的手性 C 2-对称大环,收率适中(36-53%)。通过 X 射线晶体结构分析和 CD 测量,确定了这些手性大环中双芳基基团的绝对构型。
