Thiophene isosteres: synthesis and biological evaluation of 3-substituted derivatives of 4-phenyl-2-thioxo-benzothienopyrimidine
As an extension of a previous work, in which a series of 4-phenyl-2-thioxo-benzothienopyrimidines were synthesized, a new series of 3-amino derivatives of this ring system has been prepared.The products obtained together with those reported in
