- We developed an optimized Liebeskind–Srogl reaction in order to synthesize potentially biologically active 2-aryl-1,4-dihydropyrimidines. The pallado-catalyzed cross-coupling reaction between dihydropyrimidines and tributyltin derivatives appears particularly efficient (67–95% yields) when using CuBr·Me₂S as the copper cofactor.
