SOME REACTIONS OF N-{3-[(ARYL-1-SULFONYL)IMINO]-6-OXOCYCLOHEXA-1,4-DIENE-1-YL}BENZAMIDES

N-{3-[(Aryl-1-sulfonyl)imino]-6-oxocyclohexa-1,4-diene-1-yl}benzamides have been synthesized by the reaction of the corresponding N-(4-oxocyclohexa-2,5-diene-1-ylidene)arylsulfonamides with N-chloramides with a ratio of reagents 1:2 in a solution of propan-2-one in the presence of triethylamine. The products of addition of hydrogen halides with the entry of halogen atoms in position 4 or 5 of the quinoid ring have been obtained as a result of hydrochlorination and hydrobromination of N-{3-[(aryl-1-sulfonyl)imino]-6-oxocyclohexa-1,4-diene-1-yl}benzamides. The possibility of hydrohalogenation and thiocyanation of these benzamides is determined by a steric factor. The presence of bulk substituents in the quinoid ring does not allow the introduction of a halogen atom in the 2 position of the quinoid ring. The product of aromatization of the quinoid cycle, N-{2-hydroxy-3,4-dimethyl-5-[(4-methylbenzene-1-sulfonyl)amino]phenyl}-4-methylbenzamide, was only obtained as a result of the action of hydrogen halides on 4-methyl-N-{4,5-dimethyl-3-[(4-methylbenzene-1-sulfonyl)imino]-6-oxocyclohexa-1,4-diene-1-yl}benzamide. The thiocyanate ion addition product was obtained only for 4-chloro-N-{4-methyl-3-[(4-methylbenzene-1-sulfonyl)imino]-6-oxocyclohexa-1,4-diene-1-yl}benzamide,which has a free ortho-position relative to the carbonyl carbon of the quinoid ring. The activities Insulysin inhibitor, CTGF expression inhibitor, Glutamyl endopeptidase II inhibitor, Transcription factor STAT3 inhibitor are possible for the products of hydrohalogenation and thiocyanation of N-{3-[(aryl-1-sulfonyl)imino]-6-oxocyclohexa-1,4-diene-1-yl}benzamides.
