摘要: 将数个ZSM-5基微孔-中孔催化剂用于(-)-异蒲勒醇与用作反应物和溶剂的苯甲醛进行Prins环化反应,合成杂环含氧2H-色烯衍生物,其包含四氢吡喃结构并表现出生物活性.采用N2吸附,氨-程序升温还原,吡啶和2,6-二-叔丁基吡啶吸附-脱附的红外光谱表征了所考察的催化剂.当在含适量强酸位和12倍所需产物尺寸的中孔的催化剂上,于70 oC下进行Prins反应,(-)-异蒲勒醇完全转化时所需产物产率最高达67%.

Abstract: Several ZSM-5 derived micro-mesoporous catalysts were investigated in Prins cyclisation of (-)-isopulegol with benzaldehyde acting as a reactant and a solvent for production of heterocyclic oxygen containing 2H-chromene derivatives including the tetrahydropyran structure and exhibiting biological activity. The investigated catalysts were characterized by nitrogen adsorption, ammonia temperature programmed desorption, adsorption-desorption of pyridine and 2,6-di-tert-butylpyridine with Fourier transform infrared spectroscopic control. For the Prins reaction performed at 70℃, the highest yield of the desired product, equal to 67% at complete conversion of (-)-isopulegol, was obtained over a micro-mesoporous catalyst containing an optimum amount of strong acid sites and mesopores, being 12 fold larger than the size of the desired product.
