The complex structures of the economically important group of profiset
inidin triflavanoid related phlobatannins are synthetically accessable
in a controlled biomimetic fashion via the repetitive formation of th
e interflavanyl bond and pyran ring rearrangement of the chain extende
r unit under mild alkaline conditions. Copyright (C) 1996 Elsevier Sci
