Implication

Experimental study demonstrates ruthenium-catalyzed cyclocarbonylation of yne-aldehydes into bicyclic butyrolactones, indicating an efficient catalytic route to complex ring systems.

Key Points

To develop a ruthenium-catalyzed cyclocarbonylation method transforming yne-aldehydes into bicyclic α,β-unsaturated γ-butyrolactones.
Treated yne-aldehyde substrates with triruthenium dodecacarbonyl [Ru3(CO)12] under carbon monoxide atmosphere.
Assessed reaction efficiency for constructing fused bicyclic ring frameworks from alkynyl aldehyde starting materials.
Catalyzed cyclocarbonylation effectively couples the alkyne and aldehyde moieties with carbon monoxide to assemble bicyclic α,β-unsaturated γ-butyrolactones.
Confirmed the viability of ruthenium carbonyl complexes to mediate tandem cyclization-carbonylation sequences in oxygenated polycyclic synthesis.
