3-Methoxyestra-1,3,5,8,14-pentaen-17-one (4) was prepared from 6-methoxy-1-tetralone (8) by an efficient two-pot procedure in which the D ring was generated by the Lewis acid catalysed reaction of 1,2-bis(trimethylsiloxy)cyclobutene (5) with an appropriate ketal (10). Keywords: steroid, estrone, annellation.
3-Methoxyestra-1,3,5,8,14-pentaen-17-one (4) 是由 6-甲氧基-1-四氢萘酮 (8) 通过有效的两锅法制备的,其中 D 环是由路易斯酸催化的 1,2-双(三甲基甲硅烷氧基)环丁烯 (5) 与合适的缩酮 (10) 的反应。关键词:类固醇,雌酮,环化。
