altholactone (1) led to the corresponding O-methoxymethyl derivative (3) in addition to the unexpected 6,7-dihydro-7-methoxy analogue (4), and two original tetrahydrofuranic (THF) alkyl esters ( 5,6). Moreover, when we accomplished a new method for the preparation of the furano-pyrone goniofupyrone (7) through 7-hydroxylation of 1 in acid medium, a minor compound (8) with an identical skeleton to that of compounds
altholactone的甲氧基甲基(1)导致了相应ø -甲氧基甲基衍生物(3)除了意外6,7-二氢-7-甲氧基类似物(4),和两个原始tetrahydrofuranic(THF)烷基酯(5,6) 。此外,当我们完成了一种通过在酸性介质中将1进行7-羟基化来制备呋喃并吡喃酮goniofupyrone(7)的新方法时,一种骨架与化合物5和6相同的次要化合物(8)。被确定。仔细检查已报道的具有庚内酯骨架的苯乙烯基内酯的光谱数据,发现这些结构也具有THF烷基酯骨架。通过化学相关性证实了那些结构的修饰。所有测定的内酯衍生物均证明是线粒体复合体I的特异性抑制剂。
