We report the synthesis of spiroketals by sequence of enol ether synthesis and cyclization. The enol ethers were prepared from lactones by a Julia olefination reaction, and the starting chiral lactone was prepared from an industrial intermediate. This route is a concise and efficient way to synthesize naturally occurring and biologically interesting spiroketals. We used this sequence for the preparation
我们通过烯醇醚合成和环化的顺序报告了螺缩酮的合成。烯醇醚由内酯通过 Julia 烯化反应制备,起始手性内酯由工业中间体制备。该路线是合成天然存在且具有生物学意义的螺旋酮的简洁有效的方法。我们使用这个序列来制备 SPIKET-P 和来自 Bactrocera 物种的 spiroketal。
