El-Mahdy, K. M. published the artcileConvenient Methodology for Some Heterocyclization Reactions with Thioxopyrimidine Derivatives, Application In Synthesis of 91-15-6, the main research area is fused pyrimidine heterocyclic preparation; thioxopyrimidine dimedone benzaladehyde phthalonitril eelectrophilic substitution nucleophilic reaction.
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
Russian Journal of Organic Chemistry published new progress about Electrophilic substitution reaction. 91-15-6 belongs to class nitriles-buliding-blocks, name is Phthalonitrile, and the molecular formula is C8H4N2, Application In Synthesis of 91-15-6.
