cyclopentenones have been synthesized from enynes in alcohol in the presence of a rhodium catalyst through a newly developed auto‐tandem catalytic reaction. This process combines three mechanistically distinctive reactions—an oxidation of alcohols, a decarbonylation of aldehydes, and a carbonylative [2+2+1] cycloaddition (see scheme; dppp=propane‐l,3‐diylbis(diphenylphosphane)).
