丙二烯基炔酮通过环羰基化反应条件有效地转化为稠合双环二烯二酮。Mo（CO）（6）/DMSO反应条件导致形成双环[3.3.0]辛烯酮环系统，[Rh（CO）（2）Cl]（2）催化的反应得到双环[4.3.0]-壬烯酮和双环[5.3.0]癸烯酮骨架。
Allenyl alkynones are efficiently transformed into fused bicyclic dienediones via cyclocarbonylation reaction conditions. Mo(CO)(6)/DMSO reaction conditions result in the formation of a bicyclo[3.3.0]octenone ring system, and the [Rh(CO)(2)Cl](2)-catalyzed reaction affords bicyclo[4.3.0]-nonenone and bicyclo[5.3.0]decenone scaffolds.
