synthesis of the C-18 oxygenated aspidosperma alkaloid (±)-limaspermine (3) is described using tricarbonyl-1–4-η-[1-methoxy1-4-(3-methoxycarbonylpropyl)cyclohexa-1,3-diene}iron (15) as a readily available ring C precursor. A formal synthesis of (±)-aspidospermine (1) from 4-ethylanisole, via the organoiron derivative (23) is also described as a model study for an alternative route to the C-18 functionalised
使用三羰基-1–4-η- [1-甲氧基1-4-(3-甲氧基羰基丙基)环六-1,3-二烯}铁(15)作为现成的C环前体。还描述了通过有机铁衍生物(23 )由4-乙基苯甲醚由(4-)-茴香醚(1)正式合成的方法,作为C-18官能化生物碱替代途径的模型研究。
