OLIGOMERIC FLAVANOIDS. PART 3. STRUCTURE AND SYNTHESIS OF PHLOBATANNINS RELATED TO (-)-FISETINIDOL-(4α,6)- AND (4α,8)-(+)-CATECHIN PROFISETINIDINS

Several members of the novel class of natural 'phlobaphene' condensed tannins, representing the products of c-ring isomerization of 2,3-trans-3,4-trans-(-)-fisetinidol units present in (4,6)- and (4,8)-biflavanoid profisetinidins, have been charcterized b
