Deuterium-labeled procyanidins have been prepared by hemisynthesis from taxifolin in order to investigate their metabolism in human. The structures of the desired deuterated natural compounds B3 10D (R1 = D, R2 = H) and B4 13D (R1 = D, R2 = H) were proven by spectroscopic and physical properties means, including 2H NMR spectrum. By-products with unatural absolute configuration at some centers were also formed along the process and were characterised.
