Abstract

The synthesis of 1,2,3,4,6‐penta‐O‐galloyl‐[U‐^14^C]‐D‐glucopyranose is described. [U‐^14^C] glucopyranose was reacted with tri‐O‐benzylgallic acid forming 1,2,3,4,6‐penta(tri‐O‐benzylgalloyl)‐[U‐^14^C]‐D‐glucopyranose as chromatograpically separable anomers. Removal of the benzyl group by catalytic hydrogenation afforded 1,2,3,4,6‐penta‐O‐galloyl‐[U‐^14^C]‐D‐glucopyranose in 54% overall yield. Copyright © 2002 John Wiley & Sons, Ltd.
