A regioselective enzyme-catalyzed system is selected for the synthesis of 1,3,5-trisubstituted pyrazole derivatives by adding phenyl hydrazines, nitroolefins, and benzaldehydes. The reaction is performed in a one-pot vessel with a yield ranging from 49 to 90%. TLL@MMI, immobilized lipase (TLL) on a multivariate of MOF-5/IRMOF-3 (MMI), showed good performance for the catalysis of this reaction. The prepared biocatalyst was characterized by FTIR, XRD, SEM, and EDX. The thermal and solvent stability of TLL@MMI was investigated in MeOH and EtOH after 24 h incubation. In the presence of 100% concentrations of EtOH, TLL@MMI has 80% activity.
通过添加苯肼、硝基烯烃和苯甲醛，选择了一种区域选择性酶催化体系来合成1,3,5-三取代吡唑衍生物。该反应在一锅反应容器中进行，产率在49%至90%之间。固定在多元MOF-5/IRMOF-3（MMI）上的脂肪酶（TLL），即TLL@MMI，对该反应表现出良好的催化性能。通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、扫描电子显微镜（SEM）和能谱分析（EDX）对制备的生物催化剂进行了表征。在甲醇和乙醇中孵育24小时后，研究了TLL@MMI的热稳定性和溶剂稳定性。在100%浓度的乙醇存在下，TLL@MMI具有80%的活性。
