  Enantioselective N-heterocyclic carbene catalyzed formal [3+2] cycloaddition using α-aroyloxyaldehydes and oxaziridines

  摘要：

  An enantioselective N-heterocyclic carbene catalysed formal [3+2] cycloaddition has been developed for the synthesis of oxazolindin-4-one products. The reaction of oxaziridines and alpha-aroyloxyaldehydes under N-heterocyclic carbene catalysis provides the formal cycloaddition products with excellent control of the diastereo- and enantioselectivity (12 examples, up to >95:5 dr, >99:1 er). A matched-mismatched effect between the enantiomer of the catalyst and oxaziridine was identified, and preliminary mechanistic studies have allowed the proposal of a model to explain these observations.

  efficient kinetic resolution of racemic oxaziridines has been realized via catalytic asymmetric α-hydroxylation of available β-keto esters. In the presence of a chiral bifunctional guanidine catalyst, a variety of optically active oxaziridines and chiral α-hydroxy β-keto esters were generated with excellent results (ee’s of up to 99% and 97% and yields of up to 44% and 54%, respectively).

  Asymmetric epoxidation of allylic and homoallylic amine derivatives catalyzed by Hf(IV)-bishydroxamic acid complexes is described. Under similar conditions, aldimine and ketimine produced oxaziridines. The sulfonyl group is demonstrated to be an effective directing group for these transformations.

  Chirality transformation is a basic, attractive, and important strategy for obtaining enantioenriched products with desired chiral elements. The reported chirality conversion reaction often involves the process from one type of chirality to another one. To better utilize the chirality transformation strategy for obtaining two or more products with different chiral elements in a single reaction, a new

  手性转化是获得具有所需手性元素的对映体富集产物的基本、有吸引力且重要的策略。报道的手性转化反应通常涉及从一种手性到另一种手性的过程。为了更好地利用手性转化策略在一次反应中获得两种或多种具有不同手性元素的产物，本研究提出并成功实现了一种伴随手性转化方案的动力学拆分新方法。该过程用于苯酚化合物的不对称氧化以及氧氮丙啶的动力学拆分。在所开发的方法中，顺利地以高产率和对映选择性获得了多种产品，包括轴向手性酚、氧氮丙啶和α-羟基环酮。这些产品可以很容易地用于合成各种类型的手性配体，这是其他催化不对称反应的潜在选择。

  Catalytic enantioselective oxaziridination is one of the challenging reactions in the oxidation of organic molecules. In this article, a series of novel chiral thiourea moleculars were synthesized from natural cinchona alkaloids and primary amines. By using these molecules as organocatalysts and m-chloroper-oxybenzoicacid (m-CPBA) as the oxidant, a methodology on highly enantioselective epoxidation of al-dimines has been developed. Several optically active oxaziridines have been constructed in good yields (up to 95%) and moderate to excellent enantioselectivities (up to 99% ee). A plausible transition state was also proposed.
