Combination of the Suzuki cross-coupling and nucleophilicaromatic substitution of hydrogen (SNH) reactions proved to be a convenient method for the synthesis of C(4) and/or C(5) mono(thienyl) and di(thienyl) substituted pyrimidines from commercially available 5-bromopyrimidine. All new pyrimidines were found to be active in micromolar concentrations in vitro against H37Rv, avium, terrae, rifampicin

A convenient synthetic route to novel thienoacene systems bearing a fused pyrimidine ring has been advanced. The commercially available 5-bromopyrimidine was used as the starting material to obtain various dithienoquinazoline systems through nucleophilic aromatic substitution of hydrogen (the SNH reaction), Suzuki cross-coupling, and oxidativephotocyclization. The redox and optical properties of some
