(-)-Epigallocatechin gallate (EGCg) has multiple bioactivities, and imaging/analytical tools are required for drug development studies. Here we present full details of our synthetic studies aimed at providing building blocks for development of such tools,

m-Nitrophenyltetrazole sulfone (2) was employed in the Julia-Kocienski reaction. The olefination reaction between 2 and carbonyl compounds proceeded smoothly under Masamune-Roush conditions (DBU and LiCl). These conditions were also applicable to our catechin derivative synthesis. Furthermore, phenolic mesylate was also tolerated in this mild reaction.

Optically active dihydrobenzopyran derivatives are synthesized by 6-endo cyclization of corresponding epoxy-phenol, which is readily derived from the enantioselective epoxidation of 1,3-diarylpropene. Synthetic dihydrobenzopyrans are converted into (-)-5,7-dideoxy-gallocatechin gallate as well as (-)-5,7-dideoxy-epigallocatechin derivative. Georg Thieme Verlag Stuttgart.
