PROCESSES FOR PREPARING MORPHINAN-6-ONE PRODUCTS WITH LOW LEVELS OF a,ß-UNSATURATED KETONE COMPOUNDS |
| abstract |
The present invention generally relates to processes for preparing highly pure morphinan-6-one products. The processes involve reducing the concentration of alpha, beta unsaturated ketone compounds present as impurities in morphinan 6 one products or reaction mixtures including morphinan 6 one compounds by treatment with a sulfur-containing compound. |
