异苯并呋喃(IBF)已广泛用于天然产物和多环芳烃的合成中。很少有在稠合的芳族环系统中连接两个IBF实体的例子。在这里,我们介绍了双(IBF),2,7-二(叔丁基)吡喃并[4,5- c:9,10- c ']二呋喃的合成和表征。与双(马来酰亚胺)亲二烯物的反应产生吡喃苯甲酸酯。讨论了bis(IBF)和两个环烷的固态结构。

A new oxanorbornene-fused nanobox encapsulated C70 selectively in solution with a binding constant of (3.2 ± 0.1) × 106 M−1. Reductive aromatization of this nanobox led to observation of a new zigzag carbon nanobelt by mass spectroscopy.
