The potent seed germination stimulants (+)‐strigol ( 1 ), (+)‐orobanchol ( 2 ) and their stereoisomers [2′‐epistrigol ( 1 ′), ent ‐ 1 , ent ‐ 1 ′, 2′‐epiorobanchol ( 2 ′), 4‐epiorobanchol ( 2 ′′) and 4, 2′‐bisepiorobanchol ( 2 ′′′)] were prepared from the enantiomers of 3 , which were obtainable by lipase‐catalyzed enantiomer separation of (±)‐ 3 .
