Abstract
1470703 Quinoxaline-1,4-dioxide derivatives CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEK GYARA RT 15 May 1974 [16 May 1973] 21615/74 Heading C2C Novel compounds of the Formula II wherein X is hydrogen, halogen, alkyl or alkoxy, R is hydrogen or alkyl and Ar is an aromatic ring substituted by at least one electron-donor group which is conjugated to the nitrone group, with the proviso that Ar is not halophenyl or alkylphenyl wherein alkyl and alkoxy groups have 1 to 6 carbon atoms may be prepared by reacting the corresponding 2-methyl quinoxaline-1,4-dioxide with a compound ArNO. The invention also comprises a process for preparing compounds of the Formula I wherein Q is hydroxy, -NHCONH 2 , NHCOO C 1-6 alkyl, NHCOO aryl, NHCOO aralkyl or oxazolidin-2-on-3-yl, wherein a compound of the Formula II not subject to the proviso therein is reacted with QNH 2 or its acid addition salt in the presence of an acidic substance. Some of the compounds II are active in vivo and in vitro against micro-organisms. Some of the compounds I in which Q is hydroxy are claimed in Specification 1,462,960.
