✦ Synopsis
Two erythro-isomers of 2,2%-dimethoxy-4-(3-hydroxy-1-propenyl)-4%-(1,2,3-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.
