Carbonylation of Enynes under Hydroformylation Conditions Catalyzed by Rhodium Carbonyl. A New Method for Synthesis of Cyclic Enones

Article abstract of DOI:10.1246/bcsj.61.4353

The reactivities of 1-buten-3-yne derivatives toward hydroformylation were studied using a rhodium catalyst.Unexpectedly, cyclopentenone derivatives were obtained in moderate yields together with formyl-substituted dienes and unsaturated lactones.This rea
