Abstract
A simple and efficient method for derivatization of the pyrimidine nucleus is developed. The readily available 6-amino-2-thioxo-2,3-dihydropyrimidin-4(1H)-one has been used as a versatile building block for the synthesis of thioxopyrimidine derivatives. A variety of novel fused pyrimidines has been prepared via nucleophilic and/or electrophilic reactions of thioxopyrimidine derivatives. The structures of the newly synthesized products have been deduced on the basis of elemental analysis and spectral data.
