The absolute configurations of halogenated chamigrene derivatives, isolated from L. glandulifera Kützing, 10-bromo-3,4-epoxy-α-chamigrene (1), glanduliferol (2), 10-bromo-α-chamigren-4-one (3), 4,10-dibromo-3-chloro-α-chamigrene (4) and 10-bromo-α-chamigrene (5), have been determined by X-ray diffraction analysis of 1 and subsequently, by relating 2, 3, 4 and 5 to 1 with the chemical methods. In addition
从L. glanduliferaKützing,10-bromo-3,4-epoxy-α-chamigrene(1),glanduliferol(2),10-bromo-α-chamigren-4-one(3),4,10-二溴-3-氯-α-花柏烯(4)和10-溴α-花柏烯(5),已经通过X射线衍射分析测定的1,并且随后,通过与2,3,4和5比1用化学方法。此外,(-)-α-香格里芬的绝对构型(6已经阐明了在上述化学转化过程中产生的)。
