we report the synthesis of a novelreagent designed to prepare 2-amino-5-nitrothiazole (ANT) amides and analogues in high yields. N-(Trimethylsilyl)-2-amino-5-nitrothiazole (N-(TMS)-ANT) was prepared in 99% yield via silylation of ANT using 1,1,1,3,3,3-hexamethyldisilazane (HMDS), trimethylsilyl chloride (TMSCl), and catalytic saccharin. N-(TMS)-ANT is a superb reagent for the preparation of ANT amides
在这里,我们报告了一种新型试剂的合成,该试剂旨在以高产率制备 2-氨基-5-硝基噻唑 (ANT) 酰胺和类似物。N- (三甲基甲硅烷基)-2-氨基-5-硝基噻唑 ( N- (TMS)-ANT) 通过使用 1,1,1,3,3,3-六甲基二硅氮烷 (HMDS) 甲硅烷基化 ANT 以 99% 的收率制备,三甲基氯硅烷 (TMSCl) 和催化糖精。N -(TMS)-ANT 是一种极好的试剂,可用于以极好的收率制备 ANT 酰胺。值得注意的是,环状酸酐和对碱敏感的酰氯可与N- (TMS)-ANT 一起使用,以提供通过先前报道的程序难以制备的 ANT 酰胺。
