Asymmetric direct alkynylation catalyzed by chiral Ru-bis(oxazolinyl)phenyl complexes.

Jun-ichi Ito1, Ryosuke Asai, Hisao Nishiyama.   

Abstract

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.
