Gd. Gamalevich et al., Absolute configuration and anti-hypercholesterolemic activity of (+)- and (-)-4-(2,6-dimethylheptyl)benzoic acids, RUSS CHEM B, 49(7), 2000, pp. 1313-1315
The biologically inactive (+)-enantiomer of 4-(2,6-dimethylheptyl)benzoic a
cid was converted into the known (R)-3,7-dimethyloctanol with ee greater th
an or equal to 96% by ozonolysis followed by a two-step reduction of the oz
onide. This confirmed the R configuration of the starting acid, the S confi
guration of its biologically active levorotatory antipode, and the absolute
configurations assigned to their synthetic precursors.
