Abstrakt: | New representatives of heterocyclic systems, imidazolidino[3,2-f]-pyrido-[2,3-b]- and imidazolidino[3,2-f]pyrimido[4,5-b]-1,4-thiazines, have been obtained. Intermediate compounds of 5N-oxalamides-6-hydroxy-7H-pyrido[2,3-b]-1,4-thiazine have been isolated and characterized. Amides of N-(pyridyl-3)- and N-(pyrimidyl-5)-oxaminic acids have been obtained. |
