A Pd(II)-catalyzed synthesis of furopyridines has been developed from β-ketodinitriles and alkynes via an unusual N–H/C annulation. The participation of both the nitrile groups and the concurrent construction of furan and pyridine rings through the formation of C–C, C═C, C–O, C–N, and C═N bonds are the important features. The synthetic applicability is further demonstrated through a series of postsynthetic
已经从 β-酮二腈和炔烃通过不寻常的 N-H/C 环化开发了 Pd(II) 催化的呋喃吡啶合成。腈基的参与以及通过形成 C-C、C=C、C-O、C-N 和 C=N 键同时构建呋喃和吡啶环是重要特征。通过一系列合成后改变进一步证明了合成的适用性。
