The Diels-Alder cycloadditions of trans- and cis-piperylene (1 and 2) to 4-nitroso-N-propylbenzamide (3) were selected as target reactions for the development of catalytic antibodies with regioselective and enantioselective properties (Meekel, A. A. P. Ph.D. Thesis, University of Amsterdam, 1995). The bicyclic systems 10a-c were designed as transition state analogues and employed for the immunization
选择反式和顺式-亚丙基(1和2)与4-亚硝基-N-丙基苯甲酰胺(3)的Diels-Alder环加成反应作为目标反应,以开发具有区域选择性和对映选择性的催化抗体(Meekel,AAP Ph。 D.论文,阿姆斯特丹大学,1995年。双环系统10a-c被设计为过渡态类似物,并被用于小鼠的免疫和单克隆抗体的产生。选择每种分别用不同的半抗原免疫获得的抗体中的三种,以进一步表征其催化活性。其中,针对10c蛋白缀合物的抗体309-1G7在顺式亚戊二烯(2)与亚硝基二亲烯体3的反应中显示出最佳的速率增强(kcat / kuncat = 2618)。
