8-Methyl-2-(trimethylsiloxy)tricyclo[5.3.1.03,8]undec-2-ene (11) was prepared and characterized, which is the first example of the isolable strained bridgehead enol ether of a bicyclo[3.3.1]nonan-2-one system. The reactions of 11 with electrophiles readily occurred at the C-3 bridgehead position.
制备并表征了8-甲基-2-(三甲基甲

三环[5.3.1.03,8]
十一碳烯(11),这是双环[3.3.1]可分离应变桥头烯醇醚的第一个实例非二合一系统。11与亲电试剂的反应很容易发生在C-3桥头位置。
