Kocevar, Marjan published the artcileNeighboring group participation in formation of condensed azines. Formation of pyrazolo[3,4-b]pyrazines, isoxazolo[4,5-b]pyrazines and isothiazolo[5,4-b]pyridine. Heterocycles. CCX, Synthetic Route of 56891-64-6, the main research area is neighboring group participation cyclization; azine condensed; pyrazine pyrazolo isoxazolo; pyrazolopyrazine; oxazolopyrazine; isothiazolopyridine; pyridine isothiazolo.
Pyrazine- and pyridinecarboxamidoximes with an amino or potentially tautomeric hydroxy or mercapto group in the ortho position were transformed into condensed azines. Representative pyrazolo[3,4-b]pyrazines, isoxazolo[4,5-b]pyrazines and isothiazolo[5,4-b] pyridine ring systems were synthesized and some transformations investigated.
Monatshefte fuer Chemie published new progress about Cyclocondensation reaction. 56891-64-6 belongs to class isothiazole, name is Isothiazolo[5,4-b]pyridin-3-amine, and the molecular formula is C6H5N3S, Synthetic Route of 56891-64-6.
