3-氧代-2,5,6,7-四氢环戊烷并[D]吡啶-4-甲腈 | 4-Cyano-2,3,5,6-tetrahydro-7H-cyclopenta<1,2-c>pyridin-3-one | 88745-35-1 | C9H8N2O | 160.175 |
The preparation of new substituted methyl 3-azidothieno[2,3-b]pyridine carboxylates by azotization of methyl 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, methyl 1,2,3-triazolo-thieno[2,3-b]pyridine carboxylates have been obtained.
