synthetic challenge of compounds containing the diaryl ether linkage encourages the development of new methodologies targeted toward this structural subunit. The syntheses of diaryl ethers 2 using a benzannulation strategy that formally involves a [3 + 2 + 1] cycloaddition between aryloxy-substituted Fischer carbenes 1 and alkynes are described. This methodology provides a neutral near ambient temperature formation
含二芳基醚键的化合物的
生物学相关性和不可抗拒的合成挑战鼓励开发针对该结构亚基的新方法。描述了使用苯环化策略合成二芳基醚2的方法,该策略正式涉及芳氧基取代的Fischer卡宾1与
炔烃之间的[3 + 2 + 1]环加成。该方法提供了在环境温度附近形成中性的二芳基醚的方法。
