Mollisin, a bioactive polyketide secondary metabolite of the fungus Mollisia caesia, was synthesized in nine linear steps from commercially available 2,6-dimethyl-γ-pyrone. A key transformation in this first total synthesis of mollisin was the ipso substitution of an arylstannane, which permitted the otherwise cumbersome introduction of the characteristic dichloroacetyl moiety. The fungal fungicide
Mollisin 是真菌 Mollisia caesia 的一种生物活性聚酮化合物次级代谢物,是由市售的 2,6-二甲基-γ-吡喃酮以九个线性步骤合成的。mollisin 的首次全合成中的一个关键转变是芳基锡烷的 ipso 取代,这允许引入特征性二氯乙酰基部分,否则很麻烦。以9%的总收率获得真菌杀真菌剂。
