A planar-chiral pillar[5]arene with cyclohexylmethoxy side chains and a pendant diphenylphosphine was prepared and used as a chiral ligand in asymmetric reactions. Chirality transfer from the planar-chiral pillar[5]arene scaffold to the chiral biaryl moiety was demonstrated by circular dichroism (CD) spectroscopy, single-crystal X-ray diffraction analysis, and asymmetric catalysis.

在联芳基轴上具有诱导手性的平面手性柱[5]芳烃基单膦配体

制备了具有环己基甲氧基侧链和侧基二苯基膦的平面手性柱[5]芳烃，并将其用作不对称反应中的手性配体。圆二色性 (CD) 光谱、单晶 X 射线衍射分析和不对称催化证明了从平面手性柱 [5] 芳烃支架到手性联芳基部分的手性转移。
