多环化合物的合成。第八部分 Friedel-Crafts用三羧酸的酸酐酰化。16,17-二氢-17-甲基-15 H-环戊[ a ]菲的合成
摘要:
描述了萘,1-和2-甲基萘以及1,2,3,4-四氢萘与丙烷-1,2,3-三羧酸1,2-酐及其2-甲基衍生物的酰化作用。通过这种方法已经以高收率制备了1,2,3,4-四氢-氧杂菲乙酸。中间体的结构是通过独立合成建立的。通过萘与3-甲基丁烷-1,2,4-三羧酸1,2-酐的酰化反应生成的酮酸已被用于一种新的,改进的生产16,17-二氢-17-甲基-15 H-的途径。环戊[ a ]菲(Diels烃)。由萘和2-甲基丙烷-1,2,3-三羧酸的酮酸-1,2-酐转化成外消旋的雌-1,3,5(10),6,8-五烯-17-酮[反式-(±)-3-deoxyequilenin]通过已知方法。

The facile formation of the B and C ring of rac-desoxyequilenin and of a chrysenone derivative in just one preparative step is demonstrated, applying a gold-catalyzed domino process, which involves a benzopyrylium cation as the key intermediate and an intramolecular [3+2] cycloaddition as the key step.
