SYNTHESIS OF BILOGICALLY ACTIVE 3-INDOLYL DERIVATIVES OF QUINOXALINE AND PYRIDO[2,3-B]PYRAZINE BY REACTION OF 2-(2-OXO-1,2-DIHYDRO-3H-INDOL-3-ILYDEN)ACETATES WITH 1,2-DIAMINE CYCLOHEXANE AND 2,3-DIAMINE PYRIDINE ^{[№ 12 ' 2006]}
Ethers of 2-(2-oxo-1,2-dihydro-3H-indol-3-ilyden)acetic acids interact with 1,2-diamine cyclohexane or 2,3-diamine pyridine, forming with preparative yield 2-oxo-2,3-dihydro-1H-indol-3-ilderivatives of octahydroquinoxaline-2(1H)-one and pyrido[2,3-b]pyrazine-3(2H)-one possessing strong antimicrobic activity. The structure of obtained compounds determined with the help of IK, YaMR 1H spectroscopy and mass-spectroscopy methods is being discussed.
