SYNTHESIS OF 2-PYRIDONES AND DERIVATIVES THEREOF |
| 摘要 |
2-Pyridones are conveniently synthesized from 2,4-pentadienoic acids by formation of the acid azide, decomposition of the azide into an isocyanate and the simultaneous cyclization of the isocyanate into the pyridone. The pyridones are readily converted into known pyridines.
