• Asymmetric α-oxyacylation of cyclic ketones

  Reaction of cyclic ketones with chiral N-alkyl-O-acyl hydroxylamines leads to the corresponding α-oxyacylated carbonyl compound in up to 89% ee. The levels of asymmetric induction were influenced by solvent polarity, acid strength and, to a lesser extent, temperature. Increasing the steric bulk around the nitrogen atom of the hydroxylamine reagent led to increased levels of asymmetric induction, which was also found to be detrimental to the yield observed for the transformation. Examination of N- and O-substituents along with substrates revealed the scope and limitations of the procedure.

  环酮与手性N-烷基-O-酰基羟胺的反应可生成相应的α-氧酰基羰基化合物，其对映体过量率达89%。不对称诱导的水平受到溶剂极性、酸强度以及温度（影响较小）的影响。增加羟胺试剂中氮原子周围的立体障碍，可提高不对称诱导的水平，但这也会对转化反应的产率产生不利影响。通过对N-和O-取代基以及底物的考察，揭示了该方法的应用范围和局限性。

  synthesis of α-oxygenated carbonyl compounds and catechols is the treatment of a carbonyl compound or a phenol with an electrophilic oxygen source. As an alternative approach to these important structures, formal [3,3]-rearrangements of N-enoxyphthalimides, N-enoxyisoindolinones, and N-aryloxyphthalimides have been explored. When used in combination with an initial Chan-Lam coupling, these transformations

  合成α-氧化羰基化合物和邻苯二酚的常用方法是用亲电子氧源处理羰基化合物或苯酚。作为这些重要结构的替代方法，已经研究了N-烯氧基邻苯二甲酰亚胺，N-烯氧基异吲哚满酮和N-芳氧基邻苯二甲酰亚胺的形式[3,3]重排。当与初始Chan-Lam偶联结合使用时，这些转化有助于烯基硼酸的双氧合以合成α-加氧的酮和芳基硼酸的双氧合以合成儿茶酚。N-烯氧基异吲哚啉酮的重排也已显示为非对映选择性的。
• Preparation of α-Oxygenated Ketones by the Dioxygenation of Alkenyl Boronic Acids

  Two in two: Dioxygenation of alkenyl boronic acids has been achieved with N‐hydroxyphthalimide. The two‐step process involves etherification of an alkenyl boronic acid with N‐hydroxyphthalimide followed by a [3,3] rearrangement. The dioxygenated product can then be hydrolyzed to form either the corresponding α‐hydroxy ketone or the α‐benzoyloxy ketone.

  二分之二：N-羟基邻苯二甲酰亚胺已实现了烯基硼酸的双加氧反应。分两步进行，涉及烯基硼酸与N-羟基邻苯二甲酰亚胺的醚化，然后进行[3,3]重排。然后可以将双加氧产物水解形成相应的α-羟基酮或α-苯甲酰氧基酮。

  A simple, one-pot method for the alpha-acyloxylation of carbonyl compounds that proceeds at room temperature in the presence of both moisture and air has been developed. Treatment of a variety of aldehydes and both cyclic and acyclic ketones with N-methyl-O-benzoylhydroxylamine hydrochloride provides the alpha-functionalized product in 69-92% isolated yield. The transformation is tolerant of a wide range of functional groups and, significantly, is reglospecific in the discrimination of secondary over primary centers in the case of nonsymmetrical substrates.
