Abstract (±)-5-Hydroxy-1,7-bis-(4′-hydroxyphenyl)-3-heptanone (2a), (±)-5-hydroxyl-1-(4′-hydroxyphenyl)-7-phenyl-3-heptanone (2b), (±)-5-hydroxy-7-(4′-hydroxyphenyl)-1-phenyl-3-heptanone (2c), and (±)-5-hydroxy-1,7-bis-(phenyl)-3-heptanone (2d) have been synthesized to study the structure–activity relationship regarding digestibility inhibition in vitro in cow rumen fluid. The activities were compared with the activity of chiral (S)-2a and its glucoside platyphylloside (1), isolated from Betula pendula. Compound 2a was slightly less active, 2b and 2c were more active, and 2d was less active than (S)-2a and platyphylloside.
