A new, efficient methodology for the synthesis of substituted thienylpyridines includes the synthesis of 3-thienyl-1,2,4-triazines using simple heterocyclisation followed by easy transformation of the triazine ring to a pyridine through an aza Diels–Alder approach. A variety of substituted pyridines can be easily achieved using cheap, commercially available reagents such as bromoacetylarenes, aroyl
一种新的,有效的取代噻吩基吡啶合成方法包括使用简单的杂环化合成3-噻吩基-1,2,4-三嗪,然后通过aza Diels-Alder方法将三嗪环轻松转化为吡啶。使用便宜的,可商购的试剂,例如溴乙酰芳烃,芳酰肼,降冰片二烯和烯胺以各种组合,可以容易地实现多种取代的吡啶。新的噻吩基吡啶形成磷光环金属化的Pt配合物。
