资源简介：
A novel and efficient protocol for
the regioselective synthesis
of 3-styrylcoumarins from readily available cinnamic acids and coumarins
is presented. The reaction proceeds via a decarboxylative cross-coupling
mediated by a catalytic amount of Pd(OAc)2, with Ag2CO3 as an oxidant, and with 1,10-phenanthroline
as a ligand. A plausible reaction mechanism for this process is depicted,
and the resulting 3-styrylcoumarins show excellent fluorescence quantum
yields.
