Functionalized bicyclo[3.3.0]oct-3-en-2-ones have been prepared using palladium-catalyzed telomerization of 1,3-butadiene and N,N-dimethylallylamine and palladium-catalyzed oxidative cyclization of the resulting 1,5-diene system as the key steps. The annulation affording the bicyclic skeleton was achieved by intramolecular palladium-catalyzed allylation.
功能化的双环[3.3.0]辛-3-烯-2-酮是通过钯催化的1,3-丁二烯和N,N-二甲基烯丙胺的聚合反应以及对所得1,5-二烯体系的钯催化氧化环化作为关键步骤合成的。形成双环骨架的环化反应是通过分子内钯催化的烯丙基化实现的。
