The synthesis of the racemates of the structure 1 proposed for sorgolactone and its three stereoisomers was achieved by confirming the stereostructures of the intermediate (±)-6 and the final product (±)-1 by X-ray analyses. Biological evaluation of the products employing clover broomrape (Orobanche minor) seeds revealed that the order of activity as a germination stimulant was (±)-strigol ~ (±)-9 ≤ (±)-12 > (±)-1 > (±)-11.

The first total synthesis of sorgolactone is reported, which confirms the proposed structure of the naturally occurring germination stimulant.
Synthesis of (3aR,8S,8bS,2'R)-(+)-sorgolactone and its stereoisomers, the germination stimulant from sorghum bicolor

Methyl (S)-citronellate (2) was converted to (3aR,8S,8bS,2'R)-(+)- sorgolactone (1a) by employing the radical cyclization of 6 to 7 as the key- step. Three other stereoisomers (1b, 1c and 1d) of sorgolactone were also prepared. The CD spectrum of la was in accord with that reported for the natural product.
