Processes for preparing morphinan-6-one products with low levels of alpha, beta-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 α, β-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.
