Asymmetric Alkynylation of Aldehydes Catalyzed by Bifunctional Zinc(salen) Complex
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-3', the enhanced catalytic reactivity and stereoselectivity in comparison with that of normal salen ligands in the alkynylzinc addition to aldehydes were observed.
