Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. 56-17-7, Name is 2,2′-Disulfanediyldiethanamine dihydrochloride, belongs to thiazines compound, is a common compound. In a pantent, author is Bakavoli, Mehdi, once mentioned the new application about 56-17-7, Reference of 56-17-7.
An alternative approach to the synthesis of new pyrimido[5 ‘,4 ‘:5,6][1,4]thiazino[2,3-b]quinoxaline derivatives
An alternative approach to the synthesis of a series of new pyrimido[5′,4’:5,6][1,4]thiazino[2,3-b] quinoxaline derivatives is described. Reaction of 5-bromo-2,4-dichloro-6-methylpyrimidine and 3-aminoquinoxaline-2-thiol leads to the key intermediate 3-[(5-bromo-2-chloro-6-methylpyrimidin-4-yl)thio]quinoxalin-2-amine. This intermediate can be transformed into the title ring systems by subsequent treatment either with secondary amines followed by intramolecular cyclisation or initial intramolecular cyclisation with subsequent reaction with secondary amines.
I am very proud of our efforts over the past few months and hope to 56-17-7 help many people in the next few years. Reference of 56-17-7.
