A broad scope synthesis of cyclobutanones by gold(I)-catalyzed [2 + 2] cycloaddition of ynol ethers with alkenes has been developed. We also found that internal aryl ynol ethers can undergo (4 + 2) cycloaddition reaction with alkenes leading to the corresponding chromanes.
已开发出通过金（I）催化的炔醇醚与烯烃的[2 + 2]环加成反应广泛合成环丁酮的方法。我们还发现，内芳基炔醇醚可与烯烃发生（4 + 2）环加成反应，生成相应的色满。
