The combination of the Suzuki–Miyaura cross-coupling and nucleophilic aromatic substitution of hydrogen reactions is a versatile tool for the syntheses of 4-(1R-pyrrol-2-yl)- and 4-(1R-indol-3-yl)-5-(hetero)aryl-substituted pyrimidines from commercially available 5-bromopyrimidine. The SNH [AE, (addition–elimination)] and SNH [AO, (addition–oxidation)] reactions of 5-bromopyrimidine with pyrroles and

In this paper we wish to report a highly selective and benign method for the double C-H/C-H coupling of azaaromatics with indoles or pyrrole in the presence of air oxygen/TiO2,...
