4-Bromomethyldimethylsiloxy-2,8,8-trimethyldec-1-en-5,9-diyne 11 is prepared and its radical cyclisation leads to a stereoselective synthesis of a hydrindene framework 13via three consecutive 5-exo-dig, 5-exo-trig and 6-exo-dig radical processes.
制备了4-溴甲基二甲基硅氧基-2,8,8-三甲基癸-1-烯-5,9-二炔11,通过三个连续的5-外二聚体、5-外三聚体和6-外二聚体自由基过程,其自由基环化导致了一种氢化茚框架13的立体选择性合成。
