developed. The synthesis of amide coupling derivatives prepared by (6a, 6b, 6c, 6d) was coupled with N‐ethylpiperazine to afford (7a, 7b, 7c, 7d) and morpholine to afford (8a, 8b, 8c, 8d) by using 1‐[Bis(dimethylamino)methylene]‐1H‐1,2,3‐triazolo[4,5‐b]pyridinium 3‐oxid hexafluorophosphate (HATU) and N,N‐diisopropylethylamine (DIPEA) in dichloromethane at room temperature for 10 h. The derivatives (6a, 6b
在这里,我们论证了含有1,2,3-三唑衍生物(7a,7b,7c,7d,8a,8b,8c,8d和12a,12b,12c,12d的新型吡嗪的设计和合成),按照程序中所述,使用合成的各种化学药品,碱和催化剂,均具有出色的收率(78-92%)。这种方法的开发简单,有效且易于处理。还开发了在用于酰胺和酯键形成的通用偶联剂下更温和的反应条件和更高的选择性。由(6a,6b,6c,6d)制备的酰胺偶联衍生物的合成与N-乙基哌嗪偶联得到(7a,7b,7c,7d)和吗啉得到(8a,8b,8c,8d)通过在二氯甲烷中使用1- [双(二甲基氨基)亚甲基] -1 H -1,2,3-三唑并[4,5- b ]吡啶3-氧化六氟磷酸盐(HATU)和N,N-二异丙基乙胺(DIPEA)在室温下10小时。通过在室温下在二氯甲烷(DCM)中使用N,N'-二环己基碳二亚胺和4-二甲基氨基吡啶,将衍生物(6a,6b,6c,6d)与醇(
