Stereoselective synthesis of secondary and tertiary propargylic alcohols induced by a chiral sulfoxide auxiliary

•This method is possible to obtain a chiral propargylic alcohols which is important as a synthetic intermediate.•Stereoselective alkynylation accomplished without additives.•Aldehyde as well as ketone can be used as a substrate.•Desulfurization was achieved with mild condition.•Chiral propargylic alcohol with various substituents was synthesized.
