Abstract

The first example of intramolecular diastereoselective domino reaction of ferrocene 1,1'-bis-enone to [5]ferrocenophane initiated with sodium ethoxide was found. The product is [5]ferrocenophane with two pyridyl and one ethoxy substituents arranged asymmetrically in a five-carbon bridge. Diffraction studies showed that ferrocene is in almost ideal eclipsed conformation. The fan conformation found in the crystal is also preserved in solution, which was determined by NMR spectroscopy.

新型 [5]ferrocenophane 的合成与结构

摘要首次发现了二茂铁 1,1'-双烯酮与乙醇钠引发的[5]二茂铁分子内非对映选择性多米诺反应。生成物是[5]二茂铁，其中两个吡啶基和一个乙氧基取代基不对称地排列在五碳桥上。衍射研究表明，二茂铁几乎处于理想的黯灭构象。通过核磁共振光谱测定，晶体中的扇形构象在溶液中也得以保留。
