functionalized [2.2](1,4)phenanthrenoparacyclophanes are described: either the parent system 2 is subjected to electrophilic substitution (bromination, Friedel–Crafts acylation, Rieche formylation: preparation of 5, 6, 7, 11 and 12) or the desired substituents are incorporated in the early stages of the synthesis by the preparation of the corresponding functionalized styryl paracyclophanes and their photocyclization
描述了制备功能化 [2.2](1,4) 菲并环芳烃的两种途径:母体系统 2 进行亲电取代(溴化、Friedel-Crafts 酰化、Rieche 甲酰化:制备 5、6、7、11 和 12)或在合成的早期阶段通过相应的官能化苯乙烯基对环芳烃的制备和它们的光环化成各自的菲环芳烃并入所需的取代基。通过这些特定的路线,合成了各种溴化物(22a,b)、醚(28a-c)和苯酚(29a,b)。后一种衍生物在氧化时提供对 - (31) 和邻醌 (30, 32, 33),它们是制备含有吩嗪亚基 (36) 的环烷的有用底物。茋菲光环化也可用于从各自的前体制备苯并噻吩,例如43和44。(© Wiley-VCH Verlag GmbH & Co.
