Abstract
The stereoselective synthesis of spiroannulated cyclopentenones by the Pauson–Khand reactions on hexose and pentose derived enynes was achieved under carbon monoxide free conditions using a stoichiometric quantity of Co2(CO)8. The cobalt complex of the alkyne was cleaved using dimethoxyethane–acetonitrile at 85 °C to furnish spiroannulated cyclopentenones in 75–94% yields.
