چکیده (انگلیسی):

The synthesis and characterization of new complex monoaza and pentaaza angular phenothiazine derivatives is reported. The first derivative, 6,10-dichloro-17-azadibenzo[a,n]triphenodithiazin-5,11-dione 10 was obtained by a base-catalyzed reaction of 2,6-diaminopyridine-3,5-dithiol 5 and 2,3-dichloro-1,4-naphthaquinone 9, while the second derivative, 7,9,15,17-tetraamino-6,8,16,18,25-pentazadibenzo[a,n]di([1,4]benzothaizino[3,2-c,l])triphenodiathizine 11 was obtained by the reaction of two moles of 2, 4, 6-triaminopyrimidine-3-thiol 8 and one mole of compound 10 under the same reaction conditions. The assigned structures to the above synthesized compounds were done on the basis of spectroscopic analysis.
