摘要
The fully substituted cyclopentenedione core of madindoline A （1） and B （2） as potent and selective inhibitor of IL-6 has been synthesized efficiently. The quaternary carbon center C-2＇ was constructed on the basis of a newly developed AIEt3-promoted tandem reductive rearrangement of α-hydroxy epoxides.
