含有二芳基醚键的化合物的生物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,该策略形式上涉及芳氧基取代的费歇尔卡宾1和炔之间的[3 + 2 + 1]环加成。该方法提供了二芳基醚的中性近环境温度形成。
The biological relevance and irresistible synthetic challenge of compounds containing the diaryl ether linkage encourages the development of new methodologies targeted toward this structural subunit. The syntheses of diaryl ethers2using a benzannulation strategy that formally involves a [3 + 2 + 1] cycloaddition between aryloxy-substituted Fischer carbenes1and alkynes are described. This methodology provides a neutral near ambient temperature formation of diaryl ethers.
