Asymmetric Mannich-type reaction of hydrazones with difluoroenoxysilanes using chiral zinc(II)âimidazolineâphosphine complexes as catalysts have been established, giving the corresponding adducts in good to excellent enantioselectivity and chemical yields under mild conditions.
已经建立了使用手性锌(II)–亚咪唑啉–膦配合物作为催化剂的肼酮与二氟烯氧基硅烷的不对称Mannich反应,在温和条件下可以获得相应的加成产物,表现出良好到优异的选择性和化学收率。
