  Synthesis of α-Keto-Imides via Oxidation of Ynamides

  摘要：

  A de novo preparation of alpha-keto-imides via ynamide oxidation is described. With a number of alkyne oxidation conditions screened, a highly efficient RuO2-NaIO4 mediated oxidation and a DMDO oxidation have been identified to tolerate a wide range of ynamide types. In addition to accessing a wide variety of a-keto-imides, the RuO2-NaIO4 protocol provides a novel entry to the vicinal tricarboryl motif via oxidation of push-pull ynamides, and imido acylsilanes from silyl-substituted ynamides. Chemoselective oxidation of ynamides containing olefins can be achieved by using DMDO, while the RuO2-NaIO4 protocol is not effective. These studies provide further support for the synthetic utility of ynamides.

  The key step in this transformation involves in situ generation of N-acyliminium ion (NAI) precursor under catalyst and solvent-free conditions and their further transformations promoted by superacid in the same pot. We have also presented the experimental evidence for the involvement of proto-solvated novel exocyclic N-acyliminium ion. Further, the UV–visible and fluorescence studies revealed that

  Although aerobic oxidative acylation of amides with alcohols would be a good complement to classical synthetic methods for imides (e.g., acylation of amides with activated forms of carboxylic acids), to date, there have been no reports on oxidative acylation to produce imides. In this study, we successfully developed, for the first time, an efficient method for the synthesis of imides through aerobic oxidative acylation

  尽管酰胺与醇的有氧氧化酰化是对酰亚胺的经典合成方法（例如，用活化形式的羧酸酰化酰胺）的良好补充，但迄今为止，还没有关于氧化酰化生产酰亚胺的报道。在本研究中，我们首次成功开发了一种采用 CuCl/TMEDA/nor-AZADO 催化剂体系（TMEDA = 四甲基乙二胺；nor-AZADO = 9-氮杂金刚烷N-氧基)。所提出的酰化通过以下顺序反应进行：醇有氧氧化成醛，酰胺与醛亲核加成形成半酰胺中间体，以及半酰胺中间体有氧氧化得到相应的酰亚胺。该催化系统利用O 2作为终端氧化剂并产生水作为唯一的副产物。实现这种有效酰化系统的一个重要点是TMEDA配体的利用，据我们所知，该配体尚未在之前报道的Cu/配体/ N-氧基系统中使用。基于实验证据，我们认为 TMEDA 的可能作用包括促进半酰胺氧化和从 Cu I物种再生活性 Cu II -OH 物种。这里促进半酰胺氧化尤其重要。利用所提出的系统，可以从醇
