RISA novel approach to synthesis of new imidazo[2',1':2,3]thiazolo[5,4-d]pyrimidines as a class of heterocyclic compounds
سال: 2017
خلاصه:
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) ...
Inhibitive assessment of 1-(7-methyl-5-morpholin-4-ylthiazolo[4,5-d]pyrimidin-2-yl)-hydrazine as a corrosion inhibitor for mild steel in sulfuric acid solution

Abstract In this study, the inhibitive effect of synthesized 1-(7-methyl-5-morpholin-4-yl-thiazolo[4,5-d]pyrimidin-2-yl)-hydrazine (MMTPH) as a new corrosion inhibitor for mild steel in 0.5 M sulfuric acid medium is ...
Regioselective synthesis of 3-Benzylthiazolo [3,2-a] pyrimidones and 3-Benzyl-thiazolo [3,2-c] pyrim
سال: 2006
خلاصه:
The reaction of 2-(prop-2-ynylsulfanyl)pyrimidone 1 with various iodobenzenes in the presence of a palladium catalyst leads to regioselective cyclization to 3-benzylthiazolo [3,2-a] pyrimidones 3. The reaction of ...
