9H-Cyclohepta[b]pyridin-9-one was used as a dienecycloaddition partner to construct [3.2.2] bicycles in a copper-catalyzed [4+2] cycloaddition. Oxygen- and nitrogen-substituted terminal, disubstituted, trisubstituted, and cyclic alkenes reacted to afford the cycloadducts as single constitutional isomers in 48–80% yields and diastereomeric ratios up to 5.6:1.
9 H-环庚基[ b ]吡啶-9-one被用作二烯环加成伙伴,以铜催化的[4 + 2]环加成反应构建[3.2.2]自行车。氧和氮取代的末端,二取代,三取代和环状烯烃发生反应,以48-80%的收率和高达5.6:1的非对映异构体比例提供作为单一结构异构体的环加合物。
