Synthesis of derivatives of pyrido[2,3-<i>d</i>]pyrimidines condensed with tetrahydropyran and tetrahydrothiopyran
Abstract
Methods have been developed for obtaining derivatives of 10-amino(oxo)-, 8,10-dioxo-, and 10-amino-8-oxo(thio)pyrano(thiopyrano) [4′,3′:4,5]pyrido[2,3-d]pyrimidine on the basis of 3-amino(benzylamino)-4-cyano (carbamoyl)pyrano(thiopyrano)[3,4-c]-pyridines.
