Highly enantioselective alkyne additions to aldehydes in the presence of 1,1′-bi-2-naphthol and hexamethylphosphoramide
It is found that the addition of hexamethylphosphoramide to the solution of an alkyne, Et(2)Zn, and (S)-1,1′-bi-2-naphthol in methylene chloride allows the generation of an alkynylzinc at room temperature and shows highly enantioselective additions to aldehydes. The mild condition for the formation...
