Two erythro-isomers of 2,2'-dimethoxy-4-(3-hydroxy-1-propenyl)-4'-(I, 2,3 -trihydroxypropyl)diphenyl ether, (7'S, 8'S)-9 and (7'R, 8'R)-9, were synthesized in seven steps, in which an improved method for the synthesis of the key intermediate 3 was developed. The absolute configuration of the target molecules was also confirmed. (C) 2002 Published by Elsevier Science Ltd.
