Abstract
A series of 1,6-disubstituted 2,5-dibromohexan-1,3,4,6-tetraones and 2,2,5,5-tetrahalogenohexan-1,3,4,6-tetraones have been obtained by the treatment of 1,6-disubstituted hexane-1,3,4,6-tetraones with bromine and chlorine. Bromination of (4Z)-6-aryl-3,4-dihydroxy-6-oxohexa-2,4-dienamides led to (2Z,4E)-2-aminocarbonyl-6-aryl-5-bromo-3,4-dihydroxy-6-oxohexa-2,4-dienoates and 6-aryl-2,5-dibromo-3,4,6-trioxohexanamides in preparative yield. The proposed structures of the reaction products were confirmed by IR, UV, 1H and 13C NMR, and mass spectrometry. The bacteriostatic activity and acute toxicity of the synthesized compounds have been studied.
