摘要

Abstract: A new method for the preparation of condensed [2, 2] paracyclophanes is discussed and realized for the case of [2.2](1, 4) phenanthrenoparacyclophane (7). This hydrocarbon may be prepared in three steps from [2.2] paracyclophane (4) by formylation, Wittig-Horner olefination, and photocyclization of the stilbene intermediate 6. The 300- MHz'H and 75-MHz I3C NMR spectra of 7 were completely assigned, without the use of ...
