ChemInform Abstract: Asymmetric Catalytic Mannich-Type Reaction of Hydrazones with Difluoroenoxysilanes Using Imidzaoline-Anchored Phosphine Ligand—Zinc(II) Complexes.
摘要：
Asymmetric Mannich-type reaction of hydrazones with difluoroenoxysilanes using chiral zinc(II)–imidazoline–phosphine complexes as catalysts have been established, giving the corresponding adducts in good to excellent enantioselectivity and chemical yields under mild conditions.
