Reaction of dehydroellagitannins (e.g. 1) with L-cysteine methyl ester (5) at room temperature yielded the condensation products (e.g. 3 and 4), together with a partial hydrolysate (e.g. 2), while heating the mixture at 80 deg C afforded 4 and the hydrolysate (2) in fairly good yields.In addition, reduction of a dehydrohexahydroxydiphenoyl ester group to a hexahydroxy-diphenoyl group with thiols is also described.

In a small group of plants a process of further metabolism of galloyl-D-glucose esters occurs in which oxidative coupling takes place between galloyl ester groups in the 1,6:2,4 or 3,6-position of D-glucopyranose in its least favoured 1C4
