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, CC, C–O, C–N,
and CN 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.
