  supramolecular system where coencapsulation of pyridine-borane with a variety of molecules including enones, ketones, aldehydes, oximes, hydrazones, and imines effects efficient reductions under basic aqueous conditions. Upon subjecting unprotected lysine to the host-mediated reductive amination conditions, we observed excellent ε-selectivity, indicating that differential guest binding within the same molecule

  超分子催化剂模仿酶的机制，在温和和水性条件下实现大的速率加速和精确的选择性。虽然在超分子宿主促进的小分子合成方面取得了重大进展，但这种反应性在复杂生物分子的化学选择性和位点选择性修饰中的应用实际上仍未得到探索。我们在这里报告了一种超分子系统，其中吡啶-硼烷与各种分子（包括烯酮、酮、醛、肟、腙和亚胺）的共包封在碱性水条件下有效减少。在将未受保护的赖氨酸置于宿主介导的还原胺化条件下后，我们观察到了出色的 ε 选择性，表明在不牺牲反应性的情况下，同一分子内的不同客体结合是可能的。受酶系统对复杂生物分子的翻译后修饰的启发，我们随后将这种超分子反应应用于 11 个氨基酸肽链和人胰岛素中单个赖氨酸残基的位点选择性标记。

  A highly diastereoselective annulation strategy for the synthesis of alicyclic ketones from diols and pentamethylacetophenone is described. This process is mediated by a commercially available iridium(III) catalyst, and provides efficient access to a wide range of cyclopentane and cyclohexane products with high levels of stereoselectivity. The origins of diastereoselectivity in the annulation reaction
