Page/Page column 12-13, (2013/03/26)
The present invention relates generally to catechin and epicatechin conjugates of formula (I). For example, a chemical synthesis process for the preparation of catechin and epi-catechin compounds, in particular of catechin and epi-catechin conjugates is disclosed. A further aspect of the invention pertains to new catechin and epi-catechin conjugate compounds.

Herein, the first enantioselective total synthesis of a number of biologically relevant (-)-epicatechin conjugates is described. The success of this synthesis relied on (i) optimized conditions for the stereospecific cyclization step leading to the catechin C ring; on (ii) efficient conjugation reactions; and on (iii) optimized deprotection sequences. These standard compounds have been subsequently used to elucidate for the first time the pattern of (-)-epicatechin conjugates present in four different human biological fluids following (-)-epicatechin absorption.
