On the basis of reaction electrophilic intermolecular cyclization cyclization preparation methods of synthesis of corresponding bromides and iodides thiazolo (thiazino) imidazolium, pyrimidinium that contains several condense cycles were elaborated. Main factors which govern the chemo-, regio- and stereoselectivity of formation new Heterocycles were determined. Conditions in order obtain to - thiazolo- and thiazinopyrimidines with several cycles in its structures which will increase opportunities of purposeful ompounds synthes of certain structure were selected. The Composition and structure of all received heterocycles Compounds were proved. Product Description popup.authors popup.nrat_date 2020-04-02 Close
