Synthesis of 9,10-substituted 3,4,10,10a-tetrahydro-2H,9H-1-oxa-4a,9- diazaphenanthrenes by reductive cyclization method

Commercially available o-phenylenediamine (1) was treated with methyl α-bromo-α-aryl acetate to obtain 3-aryl-3,4-dihydro-1Hquinoxalin- 2-one (2). The latter was reacted with benzyl bromide to obtain 4-benzyl-3-aryl-3,4-dihydro-1H-quinoxalin-2-one (3). Tr
