    • Abstract

       

      Starting from ε-methoxy-resacetophenone and adopting the procedure described in Part 1, 6:7-dihydroxy flavonols with 0,1 and 3 hydroxyls in the side-phenyl nucleus have been prepared. The characteristic properties of the group with reference to the hydroxy-compounds and their partial and complete methyl ethers are described. An alternative method starting with hydroxy-quinol has also been investigated and the simplest member of the group prepared by this method also.
