An improved process for lactonization in the preparation of statins |
| abstract |
The present invention relates to an improved and industrial friendly process for lactonization to produce compound of the Formula [I], from compound of the Formula [II] in presence of an inorganic compound as a suitable lactonizing agent, preferably alkali metal hydrogen sulfate, and crystallizing the obtained lactone product in a solvent; or treating compound of the Formula [II] in the presence of an inorganic compound preferably alkali metal hydrogen sulfate using phase transfer catalyst in heterogeneous phase followed by crystallizing the obtained lactone product in a solvent. |
