Two triply lactone-bridged 1,3,5-triphenylbenzene derivatives with solubilizing moieties have been synthesized in five and six steps from commercially available starting materials. Compounds containing the 1,3,5-triphenylbenzene core with two atom bridges are relatively unknown. This new class of pi-expanded coumarins contain triskelion architectures and X-ray crystallographic studies of one of the
从可商购的起始原料通过五步和六步合成了两个具有增溶部分的三重内酯桥连的1,3,5-三苯苯衍生物。相对未知的是包含带有两个原子桥的1,3,5-三苯苯核的化合物。这类新型的pi扩展香豆素包含triskelion结构,对其中一个triskelions的X射线晶体学研究表明1,3,5-三苯苯核具有近乎平面的几何形状。这是两个原子桥接的1,3,5-三苯苯衍生物采用平面结构的唯一已知实例。
