Summary

Nuclear oxidation of baicalein and scutellarein takes place readily in the 8-position, the partial methyl ethers being employed. Further methylation yields fully methylated ethers of the nobiletin series and demethylation the corresponding nor-compounds. For purposes of comparison these substances have also been prepared from 2∶5-dihydroxy-3∶4∶6-trimethoxy acetophenone by the Allan-Robinson method. The characteristic properties and reactions of these compounds are described.
