Abstract

Known methods of synthesis of thieno [3, 2-b] pyridines are significantly underrepresented compared to available information on thieno [2, 3-b] pyridines. 1, 2 Nevertheless, several synthetic pathways toward thieno [3, 2-b] pyridines have been previously described in the literature. 3-6 A thieno [3, 2-b] pyridine structure can be approached via several pathways (Figure 1), all of which require synthesis or in situ generation of 3-aminothiophene. ...
