  Synthesis, structure and properties of N-alkoxy-N-(1-pyridinium)urea salts, N-alkoxy-N-acyloxyureas and N,N-dialkoxyureas

  摘要：

  N-Alkoxy-N-(1-pyridinium)urea salts 3, 4 have been prepared, the conversions of N-acetoxy-N-methoxyurea 7 into N,N '-di-methoxyurea 8 and of N-n-propyloxy-N-(1-pyridinium)-N ',N '-dimethylurea chloride 6 into N,N-dimethoxy-N ',N '-dimethylurea 11 were carried out. A high pyramidality of the amide nitrogen in O-N-X groups [X = N+C5H5, OMe, OC(o)C6H4Cl-p] has been revealed by XRD studies of ureas 3b, 8 and N-p-chlorobenzoyloxy-N-n-butyloxyurea 9.

  Geminal systems. 50. Synthesis and alcoholysis of N-acyloxy-N-alkoxy derivatives of ureas, carbamates, and benzamides

  摘要：

  Procedures were developed for the synthesis of N-acyloxy-N-alkoxy derivatives of ureas, carbamates, and benzamides by the reactions of the corresponding N-alkoxy-N-chloro derivatives with sodium carboxylates in MeCN. N-Chloro-N-etlioxy-p-toluenesulfonamide was inert in this reaction. Alcoholysis of N-acyloxy-N-alkoxy derivatives of ureas, carbamates, and tert-alkylamines afforded the corresponding N,N-dialkoxy derivatives, whereas alcoholysis of N-acetoxy-N-ethoxybenzamide gave rise to alkyl benzoates.

  N-Alkoxy-N-chloroureas react with trimethyl phosphite in ether forming N-alkoxy-N-(dimethoxyphosphory)ureas. The obtained N-alkoxy-N-(dimethoxyphosphoryl)ureas are the products of the nucleophilic substitution at nitrogen. This reaction is a completely new way to receive the N-phosphorylureas synthetically. By this research the possibility of the N–P bond formation by N-alkoxy-N-chloroureas interaction with P-nucleophiles

  N-烷氧基-N-氯脲与亚磷酸三甲酯在醚中反应形成N-烷氧基-N- (二甲氧基磷酸)脲。得到的N-烷氧基-N- (二甲氧基磷酰基)脲是氮原子上亲核取代的产物。该反应是一种全新的合成得到N-磷酸脲的方法。通过这项研究，证明了 N-烷氧基-N-氯脲与P-亲核试剂相互作用形成 N-P 键的可能性。N -烷氧基- N -(二甲氧基磷酸)脲的结构已由1H、31 P和13 C NMR光谱、质谱和XRD研究。N-甲氧基-N- (二甲氧基磷酸)脲和Nn-丁氧基-N- (二甲氧基磷酸)脲的XRD研究证明了它们独特的结构特征。在这些化合物中，两个氮原子都具有平面构型。氨基甲酰基和 N-O 键位于平面内。因此，已经发现N-烷氧基-N- (二甲氧基磷酰基)脲具有许多不同于异头脲的结构特征。
