| titleOfInvention | Process for the preparation of flavone derivatives |
| abstract | The invention relates to a process for the preparation of flavone derivatives in which a 2-hydroxyacetophenone compound is metallated using a lithium compound at low temperatures and subsequently reacted with a keto compound, and where the ratio of the molar equivalents of lithium compound to the 2-hydroxyacetophenone compound functional groups to be metallated is from 1 to 1.2. The resultant β-diketone compound is subsequently cyclized with warming in an acidic medium. |
