  4,5-Dioxo-imidazolinium Cation Activation of 1-Acyl-1-carbamoyl Oximes: Access to Cyanoformamides Using Dichloroimidazolidinedione

  摘要：

  Cyanoformamides are prevalent as versatile building blocks for accessing synthetically useful intermediates and biologically active compounds. The development of a milder, simpler, and more efficient approach to cyanoformamides is nontrivial. Herein, we demonstrate the effectiveness of 4,S-dioxo-imidazolinium cation activation for transforming 1-aryl-1-carbamoyl oximes to cyanoformamides. By making use of the readily available and highly modifiable dichloroimidazolidinediones (DCIDs), this novel method of activation offers reactivity remarkably greater than that of other reported protocols, exhibits a high functional group compatibility with mild conditions, and could be scaled up easily. More than 30 examples are demonstrated with good to excellent yields in short reaction times. This research not only provides a mild and efficient alternative approach to assembling a portfolio of cyanoformamides but also extends the dichloroimidazolidinedione-mediated chemistry to encompass the C-C bond cleavage reaction.

  Secondary and tertiary cyanoformamides have been synthesized with a solvent-free approach from carbamoyl imidazoles and TMSCN. This method negates the need to use large excesses of toxic reagents and is amenable to large-scale synthesis.

  Treatment of primary amines with tetramethylphenylguanidine (PhTMG) and a cyanophosphonate at −10 °C under an atmosphere of carbon dioxide provides cyanoformamides in very high to excellent yields. The reaction proceeds efficiently within a short time. By-products were not detected in most runs and epimerization was not found when optically pure α-aminoesters were used as substrates. As an example, the reaction was applied to the synthesis of the marine natural product ceratinamine.

  在−10 °C的二氧化碳气氛下，采用四甲基苯基氨基脲（PhTMG）和氰基磷酸酯对一类胺进行处理，能够获得氰甲酰胺，产率非常高到优秀。该反应在短时间内高效进行。在大多数实验中未检测到副产物，且在使用光学纯的α-氨基酯作为底物时未发现表异构化。作为一个例子，该反应被应用于合成海洋天然产物ceratinamine。
