computations, reveal that the mode of action by which the boroxypyridine activates H2 is reminiscent of the reactivity of an intramolecular frustratedLewispair. However, it is the change in the coordination mode of the boroxypyridine upon H2 activation that allows the dissociation of the formed pyridone borane complex and subsequent hydroboration of an alkyne. This change in the coordination mode upon bond
报道了硼氧吡啶催化炔烃的无金属顺式选择性氢化。各种内部炔烃在80 bar于5 bar H 2下以良好的收率和立体选择性进行氢化。此外,本文所述的催化剂可实现末端炔烃的首次无金属半氢化反应。通过DFT计算证实的机制研究表明,硼氧基吡啶激活H 2的作用方式让人联想到分子内失意的Lewis对的反应性。但是,这是硼氧吡啶对H 2的配位模式的变化活化使得形成的吡啶酮硼烷配合物解离并随后炔烃的硼氢化。术语“硼配体配合”描述了键激活后配位模式的这种变化。

Sphingosine-1-phosphate (S1P) binds to a family of sphingosine-1-phosphate G-protein-coupled receptors (S1P1–5). The interaction of S1P with these S1Preceptors has a fundamental role in many physiological processes in the vascular and immune systems. Agonist-induced functional antagonism of S1P1 has been shown to result in lymphopenia. As a result, agonists of this type hold promise as therapeutics

corresponding α-acetoxy ketones throughgold-catalyzedintermolecular oxidation in the presence of 8-methylquinoline 1-oxide as the oxidant. The reaction probably proceeds through an α-oxo gold carbene intermolecular O–H insertion. A variety of terminal alkynes were efficiently converted into the corresponding α-acetoxy ketones throughgold-catalyzedintermolecular oxidation in the presence of 8-methylquinoline
