Saddle- and propeller-shaped macrocycles are obtained by fourfold Perkin condensations in transient high dilution of 4,4′-bis(phenylglyoxylic acid) with either 4,4′-bis(phenylacetic acid) or p-phenylenediacetic acid, followed by four-fold oxidative photocyclizations. In the saddle-shaped tetraphenanthrylene, the angle between opposite phenanthrene planes is close to the value of 90° of an ideal saddle
鞍和螺旋桨状的大环化合物通过四倍PERKIN冷凝在暂态高与任一4,4'-双稀释的4,4'-双(苯乙醛酸)(苯乙酸)或获得的p -phenylenediacetic酸,随后四折叠氧化光环化。在鞍形四菲中,相反的菲平面之间的角度接近理想鞍的90°值。在螺旋桨形双[5]螺旋烯的两个螺旋烯片段中,未取代的[5]螺旋烯的几何形状得以保留,而没有大环引发的扭曲。
