Chaouni, Wafaa published the artcileSynthesis of methyl 3-azidothieno[2,3-b]pyridine-2-carboxylates and application of the Huisgen reaction, SDS of cas: 103589-67-9, the main research area is ketone malononitrile Knoevenagel; alkylidene malononitrile preparation Vilsmeier Haack; chlorocyanopyridine preparation thioglycolate cyclocondensation bromoacetate cyclization; aminothienopyridinecarboxylate preparation sodium azide azidation; azidothienopyridinecarboxylate preparation Huisgen; triazolothienopyridinecarboxylate preparation.
The preparation of new substituted Me 3-azidothieno[2,3-b]pyridine carboxylates by azotization of Me 3-aminothieno[2,3-b]pyridine and subsequent treatment with sodium azide is described. Via Huisgen’s 1,3-dipolar cycloaddition between substituted alkynes and the prepared azides, Me 1,2,3-triazolo-thieno[2,3-b]pyridine carboxylates were obtained.
