  N-Alkyloxycarbonyl-3-aryloxaziridines: Their Preparation, Structure, and Utilization As Electrophilic Amination Reagents

  摘要：

  AbstractThis paper reports the synthesis of a series of N‐protected oxaziridines (N‐Moc, Boc, Z or Fmoc) and discusses their ability to deliver their N‐alkoxycar‐bonyl fragment to amines, enolates, sulfur, and phosphorus nucleophiles (electrophilic amination). These oxaziridines are prepared by oxidation of the corresponding imines with oxone or anhydrous MCPBA lithium salt as the source of oxygen. They transfer their N‐protected fragment to primary and secondary amines to give protected hydrazines in fair to excellent yield. The nitrogen transfer to free amino acids (in form of their R4N+ salts) is particularly fast, even at low temperature, providing L (or D) N‐protected α‐hydrazino acids. Enolates are C‐aminated to give N‐protected α‐amino ketones, esters, or amides in modest yield, due to a side aldol reaction of the unreacted enolate with the released benzaldehyde. With tertiary amines (Et3N), sulfides (PhSMe), and phosphines (Ph3P), amination and oxidation proceed in a parallel way; the amount of amination product increases when the temperature is lowered (kinetic control). Some of the factors that can orient the oxaziridine reactivity towards amination or oxidation of nucleophiles are considered.

  Electrophilic amination: preparation and use of N-Boc-3-(4-cyanophenyl)oxaziridine, a new reagent that transfers a N-Boc group to N- and C-nucleophiles

  摘要：

  We describe the preparation of the title compound 2b via aza-Wittig reaction of N-Boc-triphenyliminophosphorane (6) with 4-cyanobenzaldehyde followed by Oxone oxidation of the resulting imine 5b. Oxaziridine 2b is a stable, crystalline solid, which transfers under mild conditions its N-Boc fragment to primary and secondary amines (to give N(beta)-Boc-hydrazines) and enolates (to give N-Boc-amino derivatives).

  A novel reaction of bromonitromethane with a variety of imines in very mild conditions promoted by SmI2 and NaI to afford nitroamines or bromonitroamines is described. When these reactions were performed on sugar-based imines, the corresponding nitroamines or bromonitroamines were obtained in high yields and from moderate to good stereoselectivities. Synthetic possibilities of nitroamines were also

  2-Spiropiperidines are a highly desirable, yet under represented structure in drug discovery. 2-Spiropiperidines were synthesised in either a two-pot or one-pot reaction. In the two-pot reaction, the addition of a Weiler dianion to N-Boc imines, followed by deprotection and in situ condensation with a cyclic ketone generated functionalised 2-spiropiperidines in good to excellent yields. In the one-pot

  2-螺哌啶是非常合乎需要的，但是在药物发现中却处于代表性的结构之下。2-螺哌啶是通过两锅法或一锅法合成的。在两锅法反应中，向N- Boc亚胺中加入Weiler二价阴离子，然后脱保护并与环酮原位缩合生成官能化的2-螺哌啶核苷，收率好至极佳。在单锅反应中，在梅特兰–贾普条件下，将Chan's二烯添加到N -Boc亚胺中，然后添加碳酸氢钠和环状酮，以中等至良好的收率形成了功能化的2-螺哌啶。

  The existing methods, including electrophilic aromatic substitution and C–H activation, often require harsh reaction conditions and excess pyridine and generate multiple regioisomers. Herein, we report a method for borane-catalyzed tandem reactions that result in exclusively C3-selective alkylation of pyridines. These tandem reactions consist of pyridine hydroboration, nucleophilic addition of the resulting

  实现 C3 选择性吡啶官能化是有机化学中长期存在的挑战。现有的方法，包括亲电芳香取代和 C-H 活化，通常需要苛刻的反应条件和过量的吡啶，并产生多种区域异构体。在此，我们报告了一种硼烷催化串联反应的方法，该方法仅导致吡啶的 C3 选择性烷基化。这些串联反应包括吡啶硼氢化、所得二氢吡啶与亚胺、醛或酮的亲核加成，以及随后的氧化芳构化。由于吡啶是限制性反应物且反应条件温和，因此该方法构成了具有吡啶部分的结构复杂药物后期功能化的实用工具。

  The catalytic enantioselective addition of glyoxylate cyanohydrin to imines to afford α-keto-β-amino acid equivalents is reported. Sterically tuned aminobenzothiadiazine catalysts provided high yields and stereoselectivities (up to 100% yield, 99% ee, >99:1 dr) for both aromatic and aliphatic imines, and the stereodivergent synthesis of both diastereomers was achieved. The optimal catalytic system
