Medium-membered heterocyclic allenes were synthesized by the [3,3]sigmatropic rearrangement of cyclic thionocarbonates. Using this methodology and a novel application of a SmI2-HMPA reduction, an antifungal constituent of Sapium japonicum, methyl 8-hydroxy-5,6-octadienoate, was synthesized.
通过环状硫代碳酸酯的[3,3]σ向重排合成了中元杂环烯。使用这种方法和SmI 2 -HMPA还原的新应用,合成了日本五加的抗真菌成分,即8-羟基-5,6-辛二烯酸甲酯。
