A general synthetic route to the epi-series catechins was developed based on the reverse polarity strategy. Aromatic nucleophilic substitution reaction followed by the sulfinyl-metal exchange and cyclization enabled stereo-controlled access to various members of epi-series catechins and their 3-gallates.

Stereocontrolled synthesis of (-)-afzelechin was achieved via the Mitsunobu reaction, where complete stereospecificity was observed when an electron-withdrawing group was introduced to the para-position of the B-ring fragment. Copyright

A novel stereoselective synthetic approach to 1,4-benzodioxane lignans was reported in which (2R, 3R)- and (2D, 3S)-2-(4-hydroxyphenyl)-3-hydroxymethyl-1,4-benzodioxan-6-carbaldehyde were first synthesised.
