Novel bis-pyrimidine derivatives: Synthesis and characterization
In summary, new bis-pyrimidine derivatives (4a-g) were prepared in a three-step procedure based on 5-bromo-2,4-dichloro-6-methylpyrimidine (1) as starting material. In spite of our expectation based on our previous studies, ...
A novel approach to synthesis of new imidazo[2',1':2,3]thiazolo[5,4-d]pyrimidines as a class of heterocyclic compounds
we have presented an efficient synthetic pathway for the synthesis of new derivatives of imidazo[2ˈ,1ˈ:2,3] thiazolo[5,4-d]pyrimidin 4(a-g) via the heterocyclization of 2,5-dichloro-7-methylthiazolo[5,4-d]pyrimidine (1) ...
