Asymmetric direct alkynylation catalyzed by chiral Ru-bis(oxazolinyl)phenyl complexes.
Propargylic alcohols were obtained with excellent enantioselectivities in the asymmetric direct alkynylation of aldehydes using 5 mol % of chiral ruthenium complexes containing the chiral bis(oxazolinyl)phenyl ligand.
