新型手性相转移催化剂N-苄基溴化奎宁的合成及应用

Synthesis and application of a new chiral phase transfer catalyst N-benzyl quinine bromide

通过对天然手性物质进行修饰合成手性相转移催化剂N-苄基溴化奎宁,并对目标分子2,5-二甲基-4-(3-硝基苯)-1,4-二氢吡啶-3-甲酸乙酯-5-甲酸甲酯(nitrendipine)进行不对称催化合成,并通过红外光谱和核磁共振氢谱对化合物进行了表征,用X射线单晶衍射法测定了该化合物的晶体结构。

A chiral phase transfer catalyst, N-benzyl quinine bromide, was synthesized from natural chiral compound. And 2, 5-bimethyl-4-(3-nitrobenzene)-l, 4-bihydrogenation pyridine-3-(ethyl formate)-5-methyl formate (viz. nitrendipine) was synthesized by this chiral phase transfer catalysis, and characterized by elemental analysis, infrared spectrum, 1H nuclear magnetic resonance, and X-ray single-crystal diffraction.
