Recently I am researching about POLYHALOGENATED NITROBUTADIENES; CHEMISTRY, Saw an article supported by the Belarusian Republican Foundation for Basic Research [X18M-023]. Published in MAIK NAUKA/INTERPERIODICA/SPRINGER in NEW YORK ,Authors: Kolesnyk, IA; Petkevich, SK; Tsaryk, AD; Kurman, PV; Potkin, VI. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole. Recommanded Product: 67-51-6
The reaction of 3,4,4-trichloro-1,1-bis(3,5-dimethyl-1H-pyrazol-1-yl)-2-nitrobuta-1,3-diene with 2-aminopyridine gave a polysubstituted pyrido[1,2-a]pyrimidine derivative with an aminopyridine residue in the 2-position, whereas heterocyclization of 3,4,4-trichloro-1,1-bis(1H-benzotriazol-1-yl)-2-nitrobuta-1,3-diene with substituted 2-aminopyridines afforded 2-(1H-berrzotriazol-1-yl)pyrido[1,2-a]pyrimidines. 2-(Morpholin-4-yl), 2-amino, and 2-(2-hydroxyethylamino) derivatives of polysubstituted pyrido[1,2-a]pyrimidines were synthesized, and those containing a 2-hydroxyethylamino group were converted to the corresponding 4,5-dichloro-1,2-thiazole-1-carboxylates. Specific features of heterocyclizations of benzotriazolyl and dimethylpyrazolyl derivatives of trichloronitro-1,3-butadiene to pyrimidine and pyrazole systems were revealed.
Recommanded Product: 67-51-6. Welcome to talk about 67-51-6, If you have any questions, you can contact Kolesnyk, IA; Petkevich, SK; Tsaryk, AD; Kurman, PV; Potkin, VI or send Email.
