The structure of orobanchol, a new germination stimulant isolated from red clover ( Trifolium pratense), was proposed as 2a (tentative absolute configuration) on the basis of GC-MS comparison of the natural product with synthetic (±)- 2a. The structure of orobanchol, a new germination stimulant, was proposed as 2a on the basis of the synthesis of the various stereoisomers of 1a and 2a as the racemates.
