23-O(2)Cor)H(2)](2)[ZnCl(4)] unit. The 21,23-dioxacorrole cation is only slightly distorted from planarity. In [(iso-21,23-O(2)Cor)H(2)]Cl, the macrocycle is strongly puckered as the internal ring is contracted by two carbon atoms when compared to regular porphyrin. The chloride anion is located over the center of the macrocycle and is involved in two intra (N)H...Cl and two intermolecular (C)H...Cl interactions
5,10,15-三芳基甲氧基的氧杂类似物,即5,10,15-三芳基-21,23-二恶唑(21,23-O(2)Cor)H,其中两个吡咯环被呋喃部分取代通过缩合2,5-双(芳基羟甲基)呋喃,2-苯基羟甲基呋喃和吡咯而制得β-己内酰胺。2-苯基羟甲基呋喃用作合适的合成酮以引入呋喃环,并具有产生直接吡咯-呋喃α-α键的能力。用3-苯基羟甲基呋喃取代2-苯基羟甲基呋喃导致生成(21,23-O(2)Cor)H的非芳族异构体,即(iso-21,23-O(2)Cor)H,可容纳两个呋喃戒指。突出的呋喃通过β和β'碳原子内置在大环中,氧原子朝外。[(21,23-O(2)Cor)H(2)](2)[ZnCl(4)]和[(iso-21,X射线晶体学研究了23-O(2)Cor)H(2)] Cl。复杂的ZnCl(4)(2-)阴离子位于由[[21,23-O(2)Cor)H(2)]()的两个21,23-dioxacorr
