摘要：

Indenylruthenium(II) allenylidene complexes undergo regioselective nucleophilic additions of lithium enolates at the C-gamma atom of the unsaturated chain to afford keto-functionalized sigma-alkynyl derivatives. Enolates derived from the chiral ketones: (-)-carvone and (+)-pulegone are added regio- and diastereoselectively to give the first chiral keto-functionalized (sigma-alkynyl)ruthenium(II) complexes.
