Synthesis and Biological Evaluation of Some New Pyrimidine Derivatives
摘要:
Reaction of 2-mercaptopyrimidine 1 with ethyl chloroacetate afforded isomeric pyrimidines 2 and 3. Interaction of 3 with bifunctional nitrogen nucleophiles yielded pyrimidotriazine 5 and 7. Hydrazinolysis of 2 by hydrazine hydrate afforded hydrazinopyrimidine 8. Treatment of 8 with acetophenone gave 9. Cyclization of 9 with Vilsmeier reagent afforded the pyrazole carbaldehyde 10. Interaction of 8 with benzylidenemalononitrile and/or ethyl ethoxymethylenecyanoacetate afforded the pyrazoles 11 and 12. The reaction of 8 with p-chlorobenzaldehyde yielded 13, which was cyclized with thioglycolic acid to give thiazolidinone 14. The biological activity of selected compounds was investigated.
