An efficient Pd(II)-catalyzed oxidative annulation of 2-hydroxynaphthalene-1,4-diones and internal alkynes has been developed with high step efficiency. A broad range of functional groups are compatible with this reaction, thus providing a new entry to diverse naphtho[2,3-b]furan-4,9-dione derivatives in good to high yields.
已经开发了一种高效的Pd(II)催化的2-羟基萘-1,4-二酮和内部炔烃的氧化环化反应,具有较高的步长效率。各种各样的官能团都可与该反应相容,从而以高至高收率提供了新的各种萘并[2,3-b]呋喃-4,9-二酮衍生物的入口。
