Four‐component tandem procedure to prepare a series of dihydrotetrazolopyrimidinyl carbamides starting from diketene, amine, 5‐aminotetrazole, and aldehyde was newly developed in the presence of iodine. Most of the products were obtained in moderate to good yield after simple workup of the final reaction mixture, the scope and limitation was also probed into. J. Heterocyclic Chem., (2012).
从碘酮,胺,5-氨基四唑和醛开始,采用四组分串联法制备一系列二氢四唑并亚吡啶基氨基甲酰胺是新开发的。在对最终反应混合物进行简单的后处理后,大多数产品以中等到良好的收率获得,还探讨了范围和局限性。J.杂环化学。(2012)。
