reaction between maleimide 1 and fulvene 3 . It was shown that the system has a diastereoselectivity of 1.8:1 for NN‐4 :NX‐4 , which is contrary to the 16:1 ratio claimed by Dieckmann et al. The analysis of 1H NMR monitoring of the reaction revealed that both replicators show sigmoidal growth which is typical for auto‐catalytic systems.
我们重新评估了在马来
酰亚胺1和富烯3之间发生的自反应Diels-Alder反应中非对映选择性高的主张。结果表明,该系统对NN-4:NX-4的非对映选择性为1.8:1 ,这与Dieckmann等人声称的16:1比例相反。反应的1 H NMR监测分析表明,两个复制子均显示出S型增长,这是自动催化系统的典型特征。
