  通过质子耦合电子转移实现烯丙醇中的 1,3-烷基转位

  摘要：

  描述了一种通过 1,3-烷基转位将无环烯丙醇异构化为 β-官能化酮的方法。该反应通过光驱动的质子耦合电子转移 (PCET) 激活烯丙醇底物中的 O-H 键，随后产生的烷氧基自由基的 C-C β-断裂来进行。在断裂事件中产生的瞬态烷基自由基和烯酮受体随后通过自由基共轭加成重组以提供 β-官能化酮产物。多种带有烷基和酰基迁移基团的烯丙醇底物被成功地调节。来自机理研究的见解导致改进的反应方案提高了对具有挑战性的底物的反应性能。

  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。

  that the synthesis of stereodefined 1,3-enynes featuring a trisubstituted olefin is achieved by merging alkynes, alkynyl bromides, and redox-active N-(acyloxy)phthalimides through nickel-catalyzed reductive alkylalkynylation. Products are generated in up to an 89% yield as single regio- and E isomers. Transformations are tolerant of diverse functional groups and the resulting 1,3-enynes are amenable

  通过正交活化容易获得的底物进行炔烃的流线型双官能化开发催化多组分反应是有机化学中一个引人注目的目标。尤其是炔烃羰基化可以直接进入具有不同取代模式的有价值的1,3-烯炔。在这里，我们显示了通过合并炔烃，炔基溴化物和氧化还原活性的N-（酰氧基）邻苯二甲酰亚胺，通过镍催化的还原性烷基炔基化反应，可以合成具有三取代烯烃的立体定义的1,3-烯炔。单一区域和E生成的产品产率高达89％异构体。转化耐受各种官能团，并且所得的1，3-烯炔适合进一步加工成合成上有用的结构单元。利用烯烃系的N-（酰氧基）邻苯二甲酰亚胺，可以实施级联自由基加成/环化/炔基化方法以获得1，5-烯炔。这项研究强调了氧化还原活性酯与卤代烷烃相比在还原性炔烃双碳官能化中作为优越的烷基供体的关键作用。

  日期：——

  The decarboxylative alkylation of N-hydroxyphthalimide (NHPI) based reactive esters with olefins has been achieved via an organocatalytic strategy. Control experiments and density functional theory calculations suggest that these reactions involve a boryl-radical mediated decarboxylation pathway, which is different from the single electron transfer involved in decarboxylative alkylation reactions reported

  N-羟基邻苯二甲酰亚胺（NHPI）基反应性酯与烯烃的脱羧烷基化已通过有机催化策略实现。对照实验和密度泛函理论计算表明，这些反应涉及硼基自由基介导的脱羧途径，该途径不同于先前报道的脱羧烷基化反应中涉及的单电子转移。这种无金属的脱羧烷基化反应具有良好的功能相容性，并且通过烷基和芳基羧酸衍生物的转化说明了广泛的底物范围。
