  Dirhodium tetraacetate catalyzed carbon-hydrogen insertion reaction in N-substituted .alpha.-carbomethoxy-.alpha.-diazoacetanilides and structural analogs. Substituent and conformational effects

  摘要：

  A series of acyclic alpha-carbomethoxy-alpha-diazoacetanilides with different N-substituents, 5a-k, was prepared and the rhodium(II) acetate catalyzed reactions studied. It was found that the rhodium carbenoid reaction with these compounds occurred only at the N-substituent; when the N-substituent is a propargyl group, rhodium carbenoid addition to the triple bond is favored, resulting, ultimately, in the formation of a bicyclic furan derivative 8. With an N-(tert-butyloxycarbonyl)methyl substituent, interception of the rhodium carbenoid by the ester carbonyl oxygen occurred preferentially to give, eventually, 1,4-oxazine derivatives 9 and 9'. For N-alkyl substituents, rhodium carbenoid carbon-hydrogen (C-H) insertion into the alkyl group to give 2-azetidinone and/or 2-pyrrolidinone derivatives was observed. The chemoselectivity of the rhodium carbenoid C-H insertion can be altered by the use of the alpha-acetyl and alpha-phenylsulfonyl substituents. In these cases, exclusive C-H insertion at the N-aryl moiety resulted to give 2(3H)-indolinone products. However, the alpha-substituent effect on the chemoselectivity of the insertion reaction is easily overridden by conformational effects about the amide N-C(O) bond as revealed by the insertion reactions of the conformationally rigid compounds 20a-c. The alpha-substituent effects are reestablished when conformational rigidity is removed, as exemplified by the rhodium carbenoid insertion reactions of compounds 29a,b.

  贝尔塔尼尼盐在氮杂杂环和通过亚胺形成的还原胺化的机械化学方法中的应用

  摘要：

  我们的研究表明，使用固体试剂进行机械化学活化更有效。我们展示了贝尔塔尼尼盐（也称为醛-亚硫酸氢盐加合物）的实用性，它们是结晶，简化了制备和储存。这些盐是液体醛和酮的稳定替代品，可有效用于机械化学中的还原胺化、氮杂杂环和腙的合成。该技术的有效性拓宽了底物范围，简化了纯化，减少了反应时间，并提供了良好的产物收率。此外，亚硫酸氢盐加合物的热稳定性已通过 TGA（热重分析）分析得到证实。
