Abstract

The asymmetric alkynylation of aldehydes catalyzed by bifunctional Zn(salen) catalyst was realized. With a Kozlowski salen ligand (7e) bearing secondary basic 1‐piperidinylmethyl groups at C‐3 and C‐3β€², the enhanced catalytic reactivity and stereoselectivity in comparison with that of normal salen ligands in the alkynylzinc addition to aldehydes were observed.
