SDS of cas: 696-59-3In 2019 ,《Direct Synthesis of Multi-functional Pyrimidine, Pyrazine, and Pyridine Scaffolds via Inter-molecular and Intramolecular Annulations of 3-Amino-thieno[2,3-b]pyridine-2-carboxylate》 was published in Journal of Heterocyclic Chemistry. The article was written by El-Sayed, Hassan A.; Said, Said A.. The article contains the following contents:
A direct and facile synthesis of a new series of tricyclic and tetracyclic pyrimidine, pyrazine, and pyridine derivatives fused to thieno[2,3-b]pyridine was performed from Et carboxylate I as a synthon. The antibacterial results illustrated no significant results for the investigated compounds except compound II, which has moderate activity against Gram-pos. bacteria. The experimental process involved the reaction of 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3SDS of cas: 696-59-3)
2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. When aromatic ethers are exposed to halogen in the presence or absence of a catalyst, they undergo halogenation, such as bromination.SDS of cas: 696-59-3
