  Enantioselective synthesis of orthogonally protected (2R,3R)-(−)-epicatechin derivatives, key intermediates in the de novo chemical synthesis of (−)-epicatechin glucuronides and sulfates

  摘要：

  Ten orthogonally protected (-)-epicatechin and 3'- or 4'-O-methyl-(-)-epicatechin derivatives were prepared in a regiospecific and enantioselective manner. For each orthogonally protected (-)-epicatechin derivative, one specific phenolic hydroxyl was protected with a methoxymethyl (MOM) or p-methoxybenyzl (PMB) group and the remainder were protected as benzyl ethers. These uniquely protected (-)-epicatechin derivatives were designed to facilitate the regiospecific installation of a glucuronic acid or sulfate unit onto (-)-epicatechin after selective removal of the MOM or PMB protecting group to provide authentic standards of (-)-epicatechin glucuronides and sulfates.
