—— | 2-methyl-3-(3,4-dichlorophenyl)-N-propargyl-6-aminoquinoxaline | —— | C18H13Cl2N3 | 342.227 |
We report the preparation of novel 1,4,8-triazaphenanthrenes and show that the target compounds are efficiently obtained from the corresponding 6-aminoquinoxalines after N-propargylation followed by copper-catalyzed 6-endo-dig cycloisomerization and aromatization. The cyclization was found to be completely regioselective.
