Synthesis of Condensed Tannins. Part 3. Chemical Shifts for Determining the 6- and 8-Bonding Positions of 'Terminal' (+)-Catechin Units

Pairs of 6- and 8-functionalised (Br, OH, OAc, CO2Me, and CH2Me groups) 3',4',5,7-tetra-O-methyl-(+)-catechins available through selective bromination and debromination reactions and hence via lithio-analogues, provide diagnostic chemical shifts of their
