    Studies on Reactions of Pyrimidine Compounds. 2. Microwave-Assisted Synthesis of 1,2,3,4-Tetrahydro Derivatives
    (Taylor & Francis Ltd, 2008) Aklbas, Esvet; Aslanoglu, Furgan
    The 5-benzoyl-4,6-diphenyl-1,2,3,4-tetrahydro-2-thioxopyrimidine (la) and 5-benzoyl-4-(2-chlorophenyl)-6-phenyl-1,2,3,4-tetrahydro-2-thioxopyrimidine (1b) were synthesized using the Biginelli three-component cyclocondensation reaction of a beta-diketone, arylaldehyde, and thiourea under microwave irradiation. Thiazolopyrimidine (2), (3) and pyrimido[2,3-b]thiazine (4) derivatives were obtained by a Simple one-pot condensation reaction of starting compound 1b and 2-bromopropionic acid, bromoacetic acid and 3-bromopropionic acid, respectively. These reactions performed under microwave irradiation and conventional conditions. That study is suggested a simple anal efficient route for the preparation of 1,2,3,4-tetrahydro-2-thioxopyrimidine and derivatives.
