Condensation of (+)-(2R)-2,3-trans-3,4-trans-flavan-3,3',4,4',7-pentaol with excess of (-)-(2R)-2,3-trans-flavan-3,3',4',7-tetraol proceeds beyond the expected biflavanoid range to generate significant yields of both the 'linear' -2,3-trans-3,4-cis:2',3'-trans-3',4'-trans:2'',3''-trans-trifisetinidol and the first 'branched' -2,3-trans-3,4-cis:2',3'-trans-3',4'-trans:2'',3''-trans:3'',4''-trans:2''',3'''-trans-tetrafisetinidol.
