A Pd(II)-catalyzed three-component synthesis of 2,4,6-triarylfuro[2,3-d]pyrimidines from β-ketodinitriles, boronic acids, and aldehydes has been developed. The participation of both nitrile (−CN) groups led to the concurrent construction of furo-pyrimidine via the formation of C–C, C═C, C–O, C–N, and C═N bonds. The compounds show excellent photoluminescence properties with absorption maxima ranging from 348 to 387 nm and emission from 468 to 533 nm. The synthetic utility of the protocol was further demonstrated through a few postsynthetic manipulations.

Pd(II) 催化由 β-酮二腈、硼酸和醛三组分合成呋喃[2,3-d]嘧啶

开发了一种 Pd(II) 催化的由 β-酮二腈、硼酸和醛三组分合成 2,4,6-三芳基呋喃[2,3- d ]嘧啶的方法。两个腈（−CN）基团的参与导致通过形成 C-C、C=C、C-O、C-N 和 C=N 键同时构建呋喃嘧啶。这些化合物表现出优异的光致发光特性，最大吸收范围为 348 至 387 nm，发射范围为 468 至 533 nm。通过一些合成后操作进一步证明了该协议的合成效用。
