Starting from 2, 7-diacetyl-9, 10-dihydrophenanthrene, 2, 7-dichloromethyl-9, 10-dihydrophenanthrene was synthesized through a serie of a new compounds. By a modified Wurtz reaction the dichloromethyl compound led to hexahydro-[23] (2,7) phenanthrenophane and decahydro-[25] (2,7) phenanthrenophane. [23] (2,7) phenanthrenophane was obtained by dehydrogena tion of hexahydro-[23] (2,7) phenanthrenophane
通过一系列新化合物从2,7-二乙酰基-9,10-二氢菲开始合成2,2,7-二氯甲基-9,10-二氢菲。通过修饰的Wurtz反应,二氯甲基化合物生成六氢-[2 3 ](2,7)菲咯烷和十氢-[2 5 ](2,7)菲咯烷。通过用Pd / C对六氢-[2 3 ](2,7)菲咯烷进行脱氢制得[2 3 ](2,7)菲咯烷。这些新的环系统的结构已通过UV-,NMR-和质谱法证实。
