In Sadagopan1, the errors were published on pages 7, 8, and in Table 1.

On page 7, Section 3.2, where the article reads:

The calculated pK_a of 4 was 8.65, while that of the ammonium ion is known to be 9.3. Thus, showing it is favorable for ammonia to displace proline in the structure. An abundance of ammonia in the early atmosphere of Earth, can drive the production of 5.

It should read:

The calculated pK_a of 4 was 8.65, resulting in protonation in aqueous solution. The reason for retention of stereochemistry during aminolysis, is that the resulting species is in equilibrium with proline and 5‐cyanoxolan‐2‐one, with the latter species reacting with ammonia to form 5. These species are favored is because (1) two molecules are being produced from every molecule of 4, (2) equilibrium proline concentration is relatively low because it is reactive with many substrates, and (3) the reactant accumulates in the system.

On page 8, first column, where the article reads:

Kinetic analysis of the pathways (Table 1) suggests that both arbitrary excesses in S‐proline and R‐proline will propagate through the cycle because their respective syn‐products (si, S and re, R pathways) have a higher rate of production than their respective anti‐products (re, S and si, R pathways).

It should read:

Kinetic analysis of the pathways (Table 1) suggests that both arbitrary excesses in S‐proline and R‐proline will propagate through the cycle because their respective anti‐products (si, S and re, R pathways) have a higher rate of production than their respective syn‐products (re, S and si, R pathways).

On Table 1, the wrong kinetic model was used for calculations. The results from the transition state theory (TST) model at 338 K are shown below:

在Sadagopan 1中，错误发布在第7、8页和表1中。

在第7页，第3.2节中，文章显示为：

计算出的pK _a为4为8.65，而铵离子的pK _a为9.3。因此，显示出氨置换结构中的脯氨酸是有利的。地球早期大气中大量的氨可以推动5的产生。

它应显示为：

计算的pK _a为4为8.65，导致水溶液中的质子化。在氨解过程中保留立体化学的原因是，所得物质与脯氨酸和5-氰基氧杂-2-2-1处于平衡状态，而后者与氨反应形成5。之所以喜欢这些物种，是因为（1）从4的每个分子中都会产生两个分子；（2）脯氨酸的平衡浓度相对较低，因为它与许多底物具有反应性；（3）反应物在系统中积累。

在页8，第一列，文章内容如下：

对这些途径的动力学分析（表1）表明，S-脯氨酸和R-脯氨酸的任意过量都会在整个循环中传播，因为它们各自的副产物（si，S和re，R途径）的生产率高于它们各自的反产物（re，S和si，R途径）。

它应显示为：

对这些途径的动力学分析（表1）表明，S-脯氨酸和R-脯氨酸的任意过量都会在整个循环中传播，因为它们各自的反产物（si，S和re，R途径）的生产率高于它们各自的副产物（re，S和si，R途径）。

在表1上，错误的动力学模型用于计算。过渡态理论（TST）模型在338 K下的结果如下所示：
