Abstract
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)2Cl]2-catalyzed reaction affords bicyclo[4.3.0]nonenone and bicyclo[5.3.0]decenone scaffolds.
摘要
通过环羰基化反应条件，烯丙基炔酮可高效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，而[Rh(CO)2Cl]2催化的反应则提供双环[4.3.0]壬烯酮和双环[5.3.0]癸烯酮骨架。
