摘要 氯乙炔基膦酸二乙酯与2-取代的3-氨基-1,2,4-三唑的反应合成了一系列新的6-膦酰化的1 H-咪唑并[2,1- c ] [1,2,4]三唑通过5 -endo-dig环化。发现3-氨基-5-溴-1,2,4-三唑以另一种方式反应,导致形成相应的对称am二乙基{2-[(3-溴-1-甲基-1 H -1,2,4-三唑-5-基)氨基] -2-[(3-溴-1-甲基-1 H -1,2,4-三唑-5-基)亚氨基]乙基}膦酸酯。
Synthesis of 1-Alkyl-5-amino-1,2,4-triazoles Based on Nucleophilic Substitution and Reduction Reactions
摘要:
A series of 1-alkyl-5-amino-1H-1,2,4-triazoles were synthesized starting from 3,5-dibromo-1H- 1,2,4-triazole by alkylation and subsequent nucleophilic substitution of the 5-bromine atom by azido group, reduction of the latter to amino group, and hydrodebromination.
The present invention discloses compounds of Formula (I) wherein the variables in Formula (I) are defined as described herein. Also disclosed are pharmaceutical compositions containing such compounds and methods for using the compounds of Formula (I) in the prevention or treatment of HCV infection.
