Abstrakt: Representatives of new heterocyclic systems were obtained — pyrido[3',2':5,6][1,4]thiazino[3,4-c]- and pyrimido[5',4':5,6][1,4]thiazino[3,4-c][1,2, 4]triazines. Hydrazides of N-(pyrid-3-yl)- and N-(pyrimid-5-yl)oxamic acids were isolated and characterized. Their acylation products were investigated.
