  摘要：

  本发明提供了一种2‑甲胺基‑3‑吡啶甲醇及艾沙康唑鎓硫酸盐的新的制备工艺，具体采用将2‑甲胺‑3‑吡啶羧酸在辅助试剂存在条件下通过NaBH4还原，制备得到2‑甲胺基‑3‑吡啶甲醇，本发明所述的方法利用羧酸原位条件下转化为活性酯的中间体，再使用相对温和的还原剂NaBH4对活性酯中间体进行还原得到了对应的醇类产物，避免了危险性高的还原剂的使用，以及剧毒化合物硼烷的产生，大大提供生产安全性，并显著降低生产成本。

  自动机器学习辅助 TEMPO 催化伯醇氧化制备羧酸

  摘要：

  尽管醇氧化被认为是成熟的反应，但选择生产条件或预测未见醇的反应产率仍然是主要挑战。在此，公开了一种用于将伯醇催化氧化为相应羧酸的自动机器学习 (ML) 模型。使用高通量实验 (HTE) 生成了包含 3444 个数据的数据集，其中包含 282 种伯醇和 45 种条件。使用 HTE 数据和 105 个描述符，使用 AutoGluon（开源自动机器学习框架）和 KNIME（开源数据分析平台）执行多标签预测。对于 240 次反应的独立测试（20 种未见醇和 12 种条件的完整矩阵），AutoGluon 和用于产量预测的多标签预测 (AGMP) 表现出色。R 2为0.767，MAE为4.9%。该模型还表明，新生成的描述符（Y/N，反应反应性分类）是与产量预测最相关的描述符，为将 HTE 和 ML 集成到有机合成中提供了新的视角。
