Synthesis of all eight stereoisomers of the germination stimulant strigol

(+)-Strigol is a naturally occurring germination stimulant for the seeds of the parasitic weeds Striga and Orobanche. This paper describes the synthesis of all eight stereoisomers of strigol. The absolute configuration of these stereoisomers has been dedu

Routes to derivatives of strigol (the witchweed germination factor) modified in the 5-position

The title compounds were prepared using nucleophilic substitution in the 5- position of 5b, 6b, 11a, and lib or electrophilic addition to the diene system in 4 as key reactions. Methods for configurational assignment at C-5 and C-2′ are discussed.
