Reaction of 2-(2-oxo-2,3-dihydro-1H-indol-3-ylidene)acetic acid esters with benzene-1,2-diamine and 2-aminobenzenethiol
摘要:
2-(2-Oxo-2,3-dihydro-1H-indol-3-ylidene)acetic acid esters reacted with benzene-1,2-diamine or 2-aminobenzenethiol to give (2-oxo-2,3-dihydro-1H-indol-3-yl)-substituted 3,4-dihydroquinoxalin-2(1H)-ones or 2H-1,4-benzothiazin-3(4H)-ones.
