Buchler Glossary
Alkynylation
Alkynylation is an addition reaction in organic synthesis where a terminal alkyne adds to a carbonyl group to form an α-alkynyl alcohol. When the acetylide is formed from acetylene, the reaction gives an α-ethynyl alcohol. This process is often referred to as ethynylation.
Please find several examples of Alkynylation reactions promoted by Cinchona Alkaloids in our Buchler Chiral Catalyst Search.
