  Synthesis of Di- and Tri-Substituted Imidazole-4-carboxylates via PBu₃-Mediated [3 + 2] Cycloaddition

  摘要：

  Some new di- and trisubstituted imidazole-4-carboxylates were prepared from amidoacetic acids 3 in the present report. The key step to establish such imidazole-4-carboxylates stemmed from the PBu3-mediated [3+2] cycloaddition between in situ-generated 2-oxazolinone 4 and ethyl cyanoformate6. Our results indicated that trisubstituted imidazoles 7-20 were afforded in better yields than those of disubstituted imidazoles 21-27. Supplemental materials are available for this article.

  An efficient method for the synthesis of polyfunctional imidazoles from vinyl azides and amidine has been developed. Starting from vinyl azide and amidine, this transformation proceeds without any additives and the obtained imidazoles can be decorated with ester functional group that is a promising site for further modification.

  已经开发了一种由乙烯基叠氮化物和im合成多官能咪唑的有效方法。从叠氮化乙烯和am开始，这种转化无需任何添加剂即可进行，并且所得的咪唑可以用酯官能团修饰，该酯官能团是进一步修饰的有希望的部位。
