A seco-catechin cyclization approach to 4[rightward arrow]6-linked catechin dimers

27 October, 2014 - 15:17

Chem. Commun., 2014, 50,14371-14373
DOI: 10.1039/C4CC06390B, CommunicationGen Watanabe, Ken Ohmori, Keisuke Suzuki
A viable approach for the selective synthesis of the 4[rightward arrow]6-linked catechin dimers is described. The regioselective union of an acyclic catechin precursor (seco-catechin) and an electrophilic catechin unit was achieved. Subsequent pyran cyclization constructed the requisite 4[rightward arrow]6-linked dimeric structure. This method would serve as a facile method, accessing the 4[rightward arrow]6-linked oligocatechins.
