Keywords:
2H-1,4-benzoxazin-3(4H)-one, 1,4-dihydroquinoxalin-2-one, 2-oxo-1,2-dihydro-1H-indole, cis-trans izomerismAbstract
A method is presented for the synthesis of 3-(2-oxo-1,2-dihydro-3H-indol-3-ylidene)-1,4-dihydroquinoxalin-2-one and 2-(2-oxo-1,2-dihydro-3H-indol-3-ylidene)-2H-1,4-benzoxazin-3(4H)-one by the reaction of ethyl 2-oxoindoline-2-glyoxylate with o-aminophenol and o-phenylenediamine. Proposed reaction mechanisms are presented.
