8-8,6-6 AND 6-8 CATECHIN AND EPICATECHIN DIMERS AND METHOD FOR THEIR PRODUCTION

摘要

Novel catechin and epicatechin dimers with (8+Z 8), (6+Z 6), and (8+Z 6) linkages are prepared, as well as digallated dimers. A novel process for preparing these compounds is disclosed which involves the oxidative or reductive coupling of protected monomers.
