Silyl enol ethers react with bicyclo[1.1.0]butanes (BCBs) through Yb(OTf)3-promoted formal [2π + 2σ] cycloaddition reactions to furnish bicyclo[2.1.1]hexanes (BCHs). This new reaction tolerated a wide range of enol silyl ethers and BCBs. Furthermore, the amplification experiments and synthetic transformations of the cycloaddition compounds further highlighted their practicality.
甲硅烷基烯醇醚与双环[1.1.0]丁烷(BCBs)通过Yb(OTf) 3 -促进的正式[2π + 2σ]环加成反应反应生成双环[2.1.1]己烷(BCHs)。这种新反应可以耐受多种烯醇甲硅烷基醚和 BCB。此外,环加成化合物的扩增实验和合成转化进一步凸显了其实用性。
