structure of the macrolactone queenslandon was prepared using a novel strategy consisting of a glycolate aldol reaction and hydroboration of the derived enol ether 17 followed by Suzuki cross-coupling with an iodostyrene. After conversion of the cross-coupling product to the seco acid 22, Mitsunobu macrolactonization and protecting group manipulations led to the queenslandon model 5. [structure: see text]
大内酯昆士兰酮的完全官能化的核心结构是使用一种新的策略制备的,该策略包括乙醇酸羟醛缩醛反应和衍生的烯醇醚17的氢硼化,然后与碘代苯乙烯的铃木交叉偶联。在交叉偶联产物转化为癸二酸22之后,Mitsunobu宏观内酯化和保护基团的操纵导致了Queenslandon模型5的出现。
