  Dynamic Ligand Exchange of the Lanthanide Complex Leading to Structural and Functional Transformation:  One-Pot Sequential Catalytic Asymmetric Epoxidation-Regioselective Epoxide-Opening Process

  摘要：

  The characteristic property of the lanthanide complex, which easily undergoes a dynamic ligand exchange and alters its structure and function in situ, is described. After the completion of the catalytic asymmetric epoxidation of various a,beta-unsaturated amides 2 in the presence of the Sm-(S)-BINOL-Ph3As=O (1:1:1) complex 1 (2-10 mol %), the addition of Me3SiN3 directly to the reaction mixture led to smooth epoxide-opening at room temperature, affording the corresponding anti-beta-azido-alpha-hydroxyamide 4 in excellent overall yield (up to 99%) with complete regioselectivity and excellent enantiomeric excess (up to >99%). The key to the success of the sequential process was the in situ generation of the highly reactive samarium azide complex through dynamic ligand exchange. In situ IR spectroscopy and other experiments provided strong evidence that the samariurn azide complex was generated. In addition, the relatively high Lewis basicity of the amide moiety had a key role in the high reactivity of both the epoxidation and the epoxide-opening reactions. Examinations of other nucleophiles such as sulfur or carbon nucleophiles as well as transformations of epoxide-opened products are also described.

  使用磷腈基催化的酰胺的羟醛缩合反应

  摘要：

  我们已经开发出一种新的方法，用于使用1,3,5-三唑-2,4,6-三磷-2,2,4,4,6,6-六氯化物（TAPC）的磷直接将未活化的酰胺进行羟醛缩合/ SO 4 2-催化。反应混合物中的SO 4 2-物种提高了催化反应的速率。原则上，不需要金属源来生成催化剂，也不需要使用化学计量的酸或碱。该催化剂体系在相对酸性的条件下可操作。在酸性条件下进行反应的一个主要优点是醛和缩醛都能够通过脱水在酰胺羰基的α-碳上形成碳-碳键。

  The l-menthone-derived TADDOL phosphite 6b catalyzes highly enantioselective conjugate additions of acyl silanes to α,β-unsaturated amides. p-Methoxybenzoyl cyclohexyldimethylsilane adds to a variety of N,N-dimethyl acrylamide derivatives in the presence of the lithium salt of 6b.
