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.
强效种子萌发刺激剂 (+)-strigol (1), (+)-orobanchol (2) 及其立体异构体 [2'-epistrigol (1'), ent-1, ent-1', 2'-epiorobanchol (2) '), 4-epiorobanchol (2'') 和 4, 2'-bisepiorobanchol (2''')] 是从 3 的对映异构体制备的,它们可通过 (±)-3 的脂肪酶催化对映异构体分离获得。
