A novel method for the synthesis of epoxydibenzo[b,f][1,5]diazocines exhibiting a V-shaped molecular architecture is reported. The unique approach is based on unprecedented base-catalyzed, solvent-free autocondensation and cross-condensation of fluorinated o-aminophenones. The structure of the newly synthesized diazocines was confirmed independently by X-ray analysis and chiroptical methods. The rigidity
报道了一种合成具有 V 形分子结构的环氧二苯并 [ b , f ] [1,5]重氮辛的新方法。这种独特的方法基于前所未有的碱催化、无溶剂自缩合和氟化邻苯二甲酸的交叉缩合-氨基苯酮。通过 X 射线分析和手性光学方法独立地证实了新合成的重氮辛的结构。重氮辛支架的刚性允许将外消旋体分离成单个对映异构体,这些对映异构体在高达 140 °C 时具有热稳定性。此外,通过进行一系列典型的转化,包括过渡金属催化的反应,在不影响双半胺亚基的情况下进行,证明了重氮辛支架的惰性。
