A polycyclic ring system consisting of fused sesquiterpene and phenolic units, whose structure was found by X-ray crystallography to coincide with that which forms the nucleus of a series of natural products, can be constructed from chromone and terpene precursors via sequential conjugate addition and manganese(III)-induced 6-endo-trig radical cyclisation reactions.
通过 X 射线晶体学发现,由铬酮和萜烯前体通过连续共轭加成和锰(III)诱导的 6-endo-trig 自由基环化反应,可以构建一个由融合的倍半萜和酚单元组成的多环系统,其结构与构成一系列天然产物的核相吻合。

The polycyclic ring system which forms the nucleus of a series of sesquiterpene-phenol natural products, including the antimalarial 15-oxopuupehenol, can be constructed in racemic form in four efficient steps, the last of these being a stereoselective manganese(III) acetate-mediated radical cyclisation reaction.
