| titleOfInvention | Process for the preparation of lactones |
| abstract | An improved process for producing a large ring lactone which comprises subjecting a hydroxy acid to intramolecular condensation by the use of a 1-substituted-2-halopyridinium salt or a 1-substituted-2-haloquinolinium salt as a condensing agent in the presence of an acid captor in an anhydrous organic solvent. According to this process, a variety of lactones, even complex lactones such as macrolides can be obtained in good yields. |
