  Lipase-Catalyzed Resolution of (2R*,3S*)- and (2R*,3R*)-3-Methyl-3-phenyl-2-aziridinemethanol at Low Temperatures and Determination of the Absolute Configurations of the Four Stereoisomers

  摘要：

  Lipase-catalyzed resolution of (2R*,3S*)-3-methyl-3-phenyl-2-aziridinemethanol, (+/-)-2, at low temperatures gave synthetically useful (2R,3S)-2 and its acetate (2S,3R)-2a with (2S)-selectivity (E = 55 at -40degreesC), while a similar reaction of (2R*,3R*)-3-methyl-3-phenyl-2-aziridinemethanol, (+/-)-3, gave (2S,3S)-3 and its acetate (2R,3R)-3a with (2R)-selectivity (E = 73 at -20degreesC). Compound (+/-)-2 was prepared conveniently via diastereoselective addition of MeMgBr to tert-butyl 3-phenyl2H-azirine-2-carboxylate, (+/-)-1a, which was successfully prepared by the Neber reaction of oxime tosylate of tert-butyl benzoyl acetate 7a. The tert-butyl ester was requisite to promote this reaction. For determination of the absolute configuration of (2S,3R)-2a, enantiopure (2S,3R)-2 was independently prepared in three steps involving diastereoselective methylation of 3-phenyl-2H-azirine-2-methanol, (S)-10, with MeMgBr. The absolute configuration of (2S,3S)-3 was determined by X-ray analysis of the corresponding N-(S)-2-(6-methoxy-2-naphthyl)propanoyl derivative (S,S,S)-13.

  金催化合成的功能化吡啶，使用2H-叠氮基作为烯基硝基化合物的合成当量

  摘要：

  2 H- zi嗪很容易从相应的酮中合成，尽管在一个紧张的三元循环中嵌有一个CN键，但它们足够稳定，可以分离，储存和操作。2 H zi嗪可被视为烯基氮烯的有价值的合成等价物，但是，利用杂环基序的循环应变并涉及C cle裂解的反应N个单键仍然令人惊讶地受到限制。开发了一种金催化的反应，该反应可从易于获得的2-炔丙基2H-叠氮基衍生物形成多取代的官能化吡啶。这种转变对应于烯基氮烯到炔烃的前所未有的分子内转移，在低催化剂负载下进行，效率高，并且具有很高的官能团耐受性和广泛的底物范围。

  Additions of carbon nucleophiles to racemic α-stereogenic β-oxo acid derivatives that deliver enantiomerically enriched tertiary alcohols are valuable, but uncommon. This article describes stereodivergent Cu-catalyzed borylative cyclizations of racemic β-oxo acid derivatives bearing tethered pro-nucleophilic olefins to deliver highly functionalized cyclopentanols containing four contiguous stereogenic

  The annulation of N-cyclopropyl enamines to produce 1,4-dihydropyridine (1,4-DHP) derivatives is described. In the presence of molecular iodine (I2), an N-cyclopropyl enamine substrate undergoes iodination, opening of the cyclopropyl ring, and annulation with a second molecule of the substrate to form the 1,4-DHP product. This reaction is amenable to gram-scale operations under mild reaction conditions

  chemical reagents has played an essential role in the treatment of human diseases. However, the reagents currently used are limited to the covalent modification of cysteine and lysine residues. It is thus desirable to develop novel methods that can covalently modify other residues. Despite the fact that the carboxyl residues are crucial for maintaining the protein function, few selective labeling reactions

  通过化学试剂进行蛋白质修饰在人类疾病的治疗中发挥了重要作用。然而，目前使用的试剂仅限于对半胱氨酸和赖氨酸残基进行共价修饰。因此，需要开发可以共价修饰其他残基的新方法。尽管羧基残基对于维持蛋白质功能至关重要，但目前很少有选择性标记反应可用。在这里，我们描述了一种新型反应探针，3-苯基-2H-氮丙啶，它能够在体外和原位条件下以优异的效率对蛋白质中的羧基进行化学选择性修饰。此外，使用定量化学蛋白质组学平台对活性羧基残基进行了蛋白质组范围的分析。
